Products Description
Plate Heat Exchanger Sealing Strip, also commonly referred to as plate heat exchanger gasket in the industry, is the core sealing component for removable plate heat exchangers. It is fitted into the sealing groove of heat transfer plates. Aged or damaged Plate Heat Exchanger Sealing Strip is a common cause of fluid leakage, cross-contamination and equipment shutdown of heat exchangers.
Manufactured directly from our factory, this product separates heat transfer media and seals gaps between plates to stabilize internal flow channels and maintain heat transfer efficiency. It works for both new unit assembly and replacement during maintenance, compatible with most mainstream plate heat exchanger plate models.
Available Materials & Working Conditions
We select suitable rubber materials according to customers' media type, operating temperature and pressure. Common material options are listed below:
NBR:
Good oil resistance with moderate cost. Suitable for oil and normal clean water, widely used in HVAC and general industrial heat exchange systems.
01
EPDM:
Resistant to steam, hot water and aging. Works with hot water, steam and weak acid or alkali media, applied in HVAC and water treatment systems.
02
HNBR:
Improved temperature and pressure resistance, better resistance to medium aging. Designed for harsh medium and high temperature industrial environments.
03
FKM (Viton):
Excellent resistance to high temperature and strong corrosion. Suitable for chemical environments with strong acid, alkali and organic solvents.
04
Food-grade EPDM:
Meets hygiene requirements, used in food, beverage and pharmaceutical heat exchange applications.
05
Manufacturing Process & Structural Features
The Plate Heat Exchanger Sealing Strip is made by integrated vulcanization. The rubber body is dense with no surface bubbles, and its dimension precisely matches plate grooves.
Two main installation types are available:
- Clip-on type: Simple assembly and disassembly, saves time during maintenance replacement.
- Glue-on type: Stable bonding performance, fits some old-style plate structures.
Integrated vulcanization delivers stable resilience. The strip will not easily harden or crack under long-term heat and pressure, lowering leakage risk and reducing downtime for maintenance.

FAQ
Q: 1. How often should the Plate Heat Exchanger Sealing Strip be replaced?
A: Service life depends on medium, temperature and pressure. High temperature and corrosive media accelerate aging. Regular inspection is recommended. Replace the strip once hardening, cracks or leakage appear.
Q: 2. Can you provide samples for testing?
A: Yes, samples can be supplied for your working condition test.
Q: 3. Do you support custom sizes?
A: Yes. We can develop new moulds according to plate drawings or physical samples.
