EPDM rubber gaskets are made of ethylene propylene diene monomer (EPDM), a synthetic rubber that is known for its excellent resistance to weather, ozone, and ultraviolet (UV) light. This makes them ideal for use in outdoor applications, such as roofing, siding, and window seals. EPDM gaskets are also resistant to a wide range of chemicals, making them suitable for use in industrial applications, such as tanks, pipes, and valves.

In addition to their excellent resistance to weathering and chemicals, EPDM gaskets also have other desirable properties, such as:

• Flexibility and elasticity: EPDM gaskets can stretch and flex without breaking, making them well-suited for applications where there is a lot of vibration or movement.
• Durability: EPDM gaskets are designed to last for many years, even in harsh conditions.
• Food-grade compatibility: EPDM gaskets are available in food-grade grades that are safe for use in contact with food.

EPDM gaskets are available in a variety of shapes and sizes to fit a wide range of applications. They can be manufactured as solid, sponge, or foam rubber materials, depending on the specific requirements of the application.

Here are some of the common applications of EPDM rubber gaskets:

• Roofing: EPDM gaskets are used to seal the seams between roofing materials, such as shingles and sheet metal.
• Siding: EPDM gaskets are used to seal the joints between siding panels.
• Window seals: EPDM gaskets are used to seal windows and doors against air and water leaks.
• Tanks: EPDM gaskets are used to seal the joints between tank walls and lids.
• Pipes: EPDM gaskets are used to seal the joints between pipes and fittings.
• Valves: EPDM gaskets are used to seal the valves in water, gas, and oil pipelines.

EPDM rubber gaskets are a versatile and reliable sealing solution for a wide range of applications. Their excellent resistance to weathering, chemicals, and other harsh conditions makes them a good choice for many demanding applications.

Here is a table comparing the pros and cons of EPDM rubber gaskets and PTFE gaskets:

Overall, EPDM rubber gaskets are a good choice for most applications where a gasket is needed. They are relatively inexpensive, easy to install, and have a long lifespan. However, if you need a gasket that is resistant to high heat or cold, PTFE gaskets may be a better option.
