Gaskets and parts
What does a gasket do in a plate heat exchanger?
A gasket keeps the different media in a plate heat exchanger separated and makes sure they only flow through their intended channels.
A worn, damaged or dried-out gasket can lead to:
- External leakage
- Internal leakage (mixing of media)
- Loss of capacity
- Production loss
- Unplanned downtime
- Increased pressure drop
That is why timely replacement of gaskets, port rings and/or liners is essential for reliable operation of your installation.
We are brand-independent and tailor our approach to your installation and process conditions.

Gasket attachment types for plate heat exchangers
Plate heat exchangers come in many different makes, plate types and gasket designs. To ensure reliable sealing and fast installation, gaskets are available with various attachment systems. The most common versions are: Clip-On, Snap-On, Glued and Paraclip.
Thanks to these different attachment methods, gaskets can be fitted and replaced easily, depending on the type of heat exchanger and the application.
CLIP IN (PARACLIP)
Paraclip gaskets are attached to the heat exchanger plates with special fastening points that click into the dedicated openings in the plate. This design allows the gaskets to be fitted quickly and easily while maintaining a reliable seal.
CLIP ON
The unique design allows quick and easy clip-on fitting, ensures a reliable seal and makes removing and replacing the gasket particularly easy.
Glued
One of the most reliable attachment methods, keeping the time needed for fitting, removal and cleaning to a minimum. This helps reduce downtime during maintenance and is available for a large number of plate heat exchanger models.
Gaskets for virtually all makes and models
We supply parts for virtually all makes of plate heat exchangers, including:
When should a gasket be replaced?
Gaskets wear out due to temperature changes, chemical exposure, ageing and long-term use.
Common signs include:
✓ External leakage
✓ Internal leakage
✓ Dried-out or hardened gaskets
✓ Reduced heat exchanger performance
✓ Overhaul of an existing heat exchanger
Timely replacement prevents unplanned downtime and consequential damage.
OEM or aftermarket gaskets?
We supply both genuine OEM gaskets and high-quality aftermarket alternatives.
OEM gaskets are manufactured to the original manufacturer’s specifications.
Aftermarket gaskets are often an attractive alternative, with short lead times and good value for money.
Depending on the application, we advise on the solution that best suits your installation.
How do we identify your gasket?
Don’t have the nameplate or datasheet for your heat exchanger? In many cases we can still identify the right gasket.
This can often be done based on:
✓ Photos of the heat exchanger
✓ Photos of the existing gasket
✓ Plate dimensions (L × W and horizontal and vertical port centre distances)
✓ Make and model
✓ Process data
This often allows us to quickly offer the right replacement gasket, even without documentation.
Frequently asked questions about gaskets for plate heat exchangers
Which gasket do I need?
The right gasket material depends on the medium, temperature, pressure and application of your plate heat exchanger. See the overview of rubber types above.
Common materials are NBR, EPDM, HNBR and FKM (Viton®). If you tell us the make and model of your heat exchanger and both fluids, we will gladly help you select the right gasket for your installation.
Don’t have the nameplate? In many cases we can also identify the model from photos or dimensions.
What is the difference between NBR and EPDM?
NBR and EPDM are the most widely used rubber compounds for plate heat exchangers.
NBR is mainly used for oily media, fuels and hydraulic fluids.
EPDM is widely used for hot water, HVAC systems, steam applications, acids, caustics and various food processes.
Choosing the right material is essential for a long gasket life and reliable heat exchanger operation.
How long does a gasket last?
The service life of a gasket depends on the operating conditions.
Factors such as temperature, pressure, chemical exposure, downtime and maintenance have a major impact on service life.
In many installations gaskets last several years, but in intensive or heavy-duty applications they may need replacing sooner.
Signs such as leakage, hardening, drying out or reduced performance can indicate gasket wear.
Can I order gaskets only?
Yes.
We supply individual gaskets as well as complete gasket sets, port rings and liners for virtually all makes and models of plate heat exchangers.
If required, we can also carry out complete overhauls including chemical cleaning, crack testing (dye check), fitting of new gaskets, pressure testing and on-site work.
We also supply plates for all makes and models in virtually any type of metal.
So you are not obliged to order a complete overhaul.
Do you ship to my country?
Yes.
Rell Heat Exchanger Services supplies gaskets, plates and parts to customers in the Netherlands, Europe and many international markets.
We deliver for industrial, marine, HVAC and energy applications.
Get in touch with us for information about lead times, shipping options and delivery to your location.
Do you supply OEM gaskets?
Yes.
Depending on your requirements, we can supply both genuine OEM gaskets and high-quality alternatives.
Many customers choose a quality alternative for the shorter lead times and more attractive pricing.
We are happy to advise which solution best suits your installation, budget and application.
Can you identify the model?
In many cases, yes.
If the nameplate is missing or illegible, we can often still identify the correct model based on:
✓ Photos of the heat exchanger (an overview and a side view so we can count the plates)
✓ Photos of plates or gaskets
✓ Plate dimensions
✓ Number of plates
✓ Process data
This often allows us to offer the right gaskets, plates or other parts without you needing to know the exact model number.
