Product Description
EPDM Gaskets Plate heat exchanger gasket Resistant to hot water, water vapor
Heat Exchanger Gasket:
Base Polymer: EPDM is a synthetic elastomer composed primarily of ethylene, propylene, and a diene monomer (usually a third monomer like diene). This composition gives EPDM its characteristic flexibility, durability, and resistance to ozone, UV radiation, weathering, and aging.
Properties: EPDM gaskets are valued for their:
Weather Resistance: They withstand exposure to sunlight, ozone, and outdoor elements without degradation, making them ideal for outdoor and automotive applications.
Temperature Range: EPDM can typically operate effectively in temperatures ranging from -50°C to +150°C (-58°F to +302°F), depending on the specific formulation and application conditions.
Chemical Resistance: EPDM exhibits good resistance to water, steam, acids, alkalis, and polar solvents, though it is less resistant to petroleum-based fluids compared to NBR or HNBR.
Mechanical Properties: EPDM gaskets have excellent elasticity and can maintain their sealing capabilities over a wide range of temperatures and pressures.
Electrical Insulation: EPDM also offers good electrical insulation properties, making it suitable for certain electrical enclosure and sealing applications.

Installation method
Plate heat exchanger sealing gaskets can be divided into 3 forms according to the installation method on the heat exchange plates:
1. Direct sticking type: After applying sealant on the sealing gasket, it is directly glued into the installation groove of the heat exchange plate.
2. Plastic nail inlaid type: The heat exchange plate is designed with assembly holes, and rubber nails are designed on the side of the sealing gasket. After the sealing gasket is placed in the installation slot, the rubber nails are embedded in the assembly holes.
3. Snap-on type: There are buckles on the side of the sealing gasket, and the buckles are used to buckle the sealing gasket onto the heat exchange plate.
The sealing gasket uses different types of rubber according to different media and operating temperatures.
| Main Body Gasket | Operating Temperature (℃) | Suitable Fluid |
| NBR | -15 ~ +135 | Water, Sea water, Mineral Salt, Brine |
| EPDM | -25 ~ +180 | Hot water, Vapour, Acid, Base |
| F26 | -25 ~ +230 | Acid, Base, Fluid |
| FTP | 0 ~ +160 | Concentrated acid, Base, High temperature oil, Vapour |
| FKM | -25~200 | Steam acid,98% SO2,Cl water. |
The steps for replacing the gasket in a heating exchanger are as follows:
- Carefully remove the old gasket, ensuring that no scratches are made on the gasket groove during disassembly.
- Use butanone, or other ketone solvents to remove any residue from the gasket groove.
- Clean the gasket groove and gasket with a clean cloth or cotton swab, ensuring they are free from dirt and debris.
- Apply adhesive evenly to the gasket groove.
- Install the clean new gasket onto the plate, ensuring proper alignment.
- After installing the gasket on the plate, allow it to dry naturally in a flat, cool, and well-ventilated area before installation and use.
Q&A
Q1: Does the gaskets product come with a warranty?
A1: Gasket are consumable accessories, and the replacement cycle is generally determined according to the specific conditions of use by the customer. It is related to the use environment, medium, temperature, etc. Usually we recommend purchasing more for replacement and backup purposes.
Q2: Is there a discount available for wholesale or bulk purchases?
Answer: Yes, we offer discounts for wholesale and bulk purchases. If you are interested in purchasing a large quantity of items or engaging in wholesale business, please contact our wholesale department or customer service team for information regarding wholesale discounts and minimum purchase quantities.
