Tranter heat exchangers are widely used in industrial heating, cooling, marine, food processing and other heat-transfer applications. As installed equipment ages, many operators prefer to maintain the existing frame by replacing worn plates and gaskets rather than replacing the complete plate heat exchanger.
The GX42 / GXD-042 family is an important part of this aftermarket demand. Buyers searching for Tranter GXD042, Tranter GXD 042, Tranter GX 42, Tranter UFX 42 or Tranter UFX-42 are often trying to identify an existing unit and source compatible replacement plates, gaskets or complete plate packs.
Senovis PHE supplies compatible Tranter heat exchanger plates and gaskets for maintenance and replacement projects. Our Tranter-related RFQs show that customers often know the model number but still need to confirm plate material, plate thickness, gasket material and exact configuration before production.
This is especially important because the Tranter aftermarket extends far beyond GX42. Buyers may also search for replacement gaskets for GX, GXD, UFX, UXP, GFP, HX and HXD families, including models such as GX-60, GX-64, GXD-060, GXD-085, GXD-180, UFX-51, UFX-64, UFX-100, GFP-057, GFP-180, HX-050, HX-180 and HXD-series equipment.
This guide focuses on GX42 / GXD-042 while also explaining how Senovis PHE approaches identification and replacement-part sourcing across other Tranter PHE families.

Tranter GX 42, Tranter GXD 042 and Tranter UFX-42: Are They the Same Plate Heat Exchanger?
One of the first difficulties facing replacement-parts buyers is model identification.
An existing unit may be described in an RFQ, historical document or online search as Tranter GX 42, Tranter GXD 042, Tranter GXD042, Tranter UFX 42, Tranter UFX-42 or Tranter UFX42.
These references can provide useful clues about the plate family, but they should not automatically be interpreted as proof that every corresponding plate and gasket is interchangeable.
The same problem exists across other Tranter product families. A buyer may encounter references to GX, GXD, UFX, UXP, GFP, HX or HXD equipment, and a small difference in the model designation can point to a different plate or gasket configuration.
For this reason, Senovis PHE normally verifies replacement components using several pieces of information together:
- Full model designation
- Equipment nameplate
- Serial number
- Original P/N, if available
- Existing plate photographs
- Existing gasket photographs
- Plate length and width
- Port dimensions and positions
- Plate material and thickness
- Gasket material
- Required quantity
This is particularly important for older equipment. A description used by a plant maintenance department today may not exactly match the terminology found in historical documentation.
A buyer looking for a Tranter GXD042 UFX42 heat exchanger plate, for example, should therefore use those model references as the starting point for identification rather than the sole basis for ordering.
Tranter GXD-042 PR, Tranter GXD 042 NR, Tranter GXD 042N and Tranter GXD 042P: Why the Exact Model Matters
The characters following GXD-042 can be important when sourcing replacement parts.
Buyers may encounter Tranter GXD-042 PR, Tranter GXD 042 NR, Tranter GXD 042N, Tranter GXD 042P or simply GXD 042 NR in RFQs, technical records and online searches.
Removing these characters and ordering a generic “GXD-042 gasket” can introduce unnecessary compatibility risk.
The complete model designation may contain useful information about the heat exchanger configuration. However, the model string should still be evaluated together with the nameplate and physical parts.
This is particularly important for Tranter GXD-042 gaskets. Two units belonging to the GXD-042 family should not automatically be assumed to have identical gasket material, plate count or complete configuration.
Buyers searching for a Tranter GXD-042 PDF are often looking for dimensions, technical specifications or identification information. Technical documentation can be useful, but a PDF found online should not replace verification against the actual installed unit—especially if the PHE has been rebuilt or modified during its service life.
The same rule applies to other gasket searches. Requirements for GXD-060, GXD-085 or GXD-180 gaskets should be identified against their respective models rather than generalized from the GXD-042 family.
How to Read Tranter GXD 042 Model Numbers: GXD-042-H-5UR-73 and GXD-060-H-5-UP-377 Explained
Real RFQs illustrate why a complete Tranter model number is valuable.
Senovis PHE has handled enquiries containing detailed designations such as:
GXD-042-H-5UR-73
and
GXD-060-H-5-UP-377
The first gives considerably more information than an enquiry saying only “Tranter GXD 042.” The second immediately tells us that the requirement concerns a different GXD size and configuration.
The numerical portions of these designations can provide useful clues about the equipment and plate pack. However, a buyer should not assume that every part of a model number can be independently decoded without checking the corresponding documentation.
More importantly, the complete designation does not necessarily tell the replacement supplier everything needed for manufacturing.
For example, after receiving GXD-042-H-5UR-73, the following questions may remain:
What is the plate material?
SS304, SS316L, titanium or another alloy?
What is the plate thickness?
The model number alone should not be used to guess it.
What is the gasket material?
NBR, EPDM or another elastomer?
What is the process medium?
Water, oil, seawater or another process fluid?
What are the operating conditions?
Temperature and pressure affect material selection.
The same principle applies when a customer requests Tranter GXD-060 gaskets. Even when the basic model is known, the gasket compound and exact configuration should still be confirmed.
Senovis PHE therefore treats the model designation as the beginning of technical verification—not the end.
Tranter GXD-042 Gaskets: Why NBR Is a Popular Choice and What Other Materials Are Available?
Gaskets are among the most frequently replaced components in gasketed plate heat exchangers.
Based on Tranter replacement enquiries handled by Senovis PHE, NBR is one of the commonly requested gasket materials, including requirements associated with GXD-series equipment.
NBR is commonly considered for oils and many general industrial services when its temperature and chemical compatibility are appropriate.
However, the fact that a unit is GXD-042 does not automatically mean that it should use NBR.
Other gasket materials can include EPDM and application-specific elastomers, depending on:
- Process medium
- Operating temperature
- Operating pressure
- Cleaning chemicals
- Chemical compatibility
- Existing gasket specification
- Required service life
This principle extends across the wider Tranter gasket range.
Industrial buyers may require compatible gaskets for models such as:
GX-60 and GX-64
GXD-042, GXD-060, GXD-085 and GXD-180
UFX-51, UFX-64 and UFX-100
UXP-060
GFP-057 and GFP-180
GXP-118
HX-050 / HX-50 and HX-180
HXD-050, HXD-145 and HXD-180
These model families should not be treated as one universal gasket design. Each requirement must be matched to the correct PHE model and gasket configuration.
For a Tranter PHE gasket enquiry, Senovis PHE therefore recommends sending the complete model number and an existing gasket photograph whenever possible.
Tranter GX 42 Replacement Plates: SS304, SS316L, Titanium and SMO254 Options
Plate material is another major consideration in Tranter replacement projects.
Common plate materials across gasketed PHE applications include:
SS304 — frequently used for suitable general industrial water and process applications.
SS316L — provides greater corrosion resistance than SS304 in many industrial environments.
Titanium — particularly important for seawater and chloride-rich services.
SMO254 — a high-alloy option considered for demanding corrosive applications where conventional stainless steel may not provide sufficient resistance.
This explains why searches for Tranter GX42 replacement plates frequently contain combinations such as 304 / 316L / Ti / SMO254.
However, material alone does not establish compatibility.
A replacement plate should be checked for:
Material + Thickness + Plate Pattern + Dimensions + Port Arrangement + Quantity
The same approach applies to other Tranter plate families. GX26, GX42, GXD-060 or other PHE models require the correct tooling and geometry; a visually similar plate is not enough.
Senovis PHE therefore recommends matching the existing specification wherever possible rather than changing material or thickness simply because another option is readily available.
Titanium Tranter GX 42 Plates for Seawater Coolers and Marine Applications
Seawater is a demanding heat-transfer medium because of its chloride content and corrosive characteristics.
For plate surfaces directly exposed to seawater, titanium is widely preferred in many marine PHE applications because of its excellent resistance to chloride-rich environments.
Typical applications include:
- Marine engine cooling
- Central cooling systems
- Freshwater/seawater cooling
- Offshore equipment
- Coastal industrial facilities
- Seawater utility systems
This is why buyers may encounter product descriptions involving Tranter GX42 titanium plates for seawater coolers.
However, not every GX42 installed on a ship or offshore facility automatically requires titanium.
A PHE operating entirely in a closed freshwater circuit has different corrosion conditions from one directly exposed to seawater. The correct plate material should therefore be selected according to the actual medium and original equipment specification.
Likewise, stainless steel should not automatically be substituted for titanium simply to reduce the cost of a seawater replacement project.
For existing equipment, Senovis PHE generally recommends matching the original plate material unless a qualified engineering review supports a change.
Tranter GX 42 Plate Heat Exchangers for Food, Dairy and Milk Pasteurizer Equipment
Tranter-type gasketed PHEs can also be used in food and dairy processing.
Plate heat exchangers are attractive for suitable food applications because they provide efficient heat transfer within a compact footprint and allow the plate pack to be serviced.
Typical duties can include:
- Milk heating and cooling
- Dairy processing
- Pasteurization
- Process-water heating
- Food-industry utility systems
- Heat recovery
Material selection still depends on the actual process.
Stainless steel is commonly used in many food-processing heat exchangers, while titanium or other materials may be selected when the process chemistry or corrosion environment requires them.
Gasket selection also needs to consider the process fluid, operating temperature and cleaning chemicals.
For food and dairy replacement projects, customers may additionally request material traceability or applicable food-contact documentation. These requirements should be confirmed before ordering so that the product specification and documentation package can be prepared together.
Replacement Parts for Tranter GX 42 and Other Gasketed Plate Heat Exchangers
The Tranter aftermarket extends far beyond GX42.
Industrial operators and distributors may need replacement parts for numerous equipment families, and gasket searches frequently involve models such as UFX-51, UFX-64, UFX-100, GX-60, GX-64, GXD-060, GXD-085, GXD-180, GFP-057, GFP-180, GXP-118, UXP-060, HX-050, HX-180, HXD-050, HXD-145 and HXD-180.
Typical requirements include:
Replacement plates
Replacement gaskets
Complete plate packs
Plate-and-gasket combinations
Maintenance spare-part quantities
This broad model range is one reason why simply asking for “Tranter heat exchanger gaskets” is often insufficient for a precise quotation.
A useful RFQ should ideally contain:
Model | P/N | Plate Material | Plate Thickness | Gasket Material | Quantity
If those details are unavailable, the buyer can send:
Nameplate + Plate Photo + Gasket Photo + Dimensions
The same logic applies to older or related equipment such as Tranter GXD 026, Tranter GCP 026, Tranter GXD-051 and Tranter GCP 051.
Similarly, buyers considering a replacement for Tranter GX26/GX42 plate heat exchangers should first evaluate the condition of the existing frame. If the frame remains serviceable, replacing plates and gaskets may be more economical than purchasing a complete PHE.
If the frame is severely corroded, mechanically damaged or no longer suitable for the required capacity, a complete replacement heat exchanger may be the better option.
