EPDM Rubber Parts: Gaskets, Grommets, and More
EPDM rubber is a high-density synthetic rubber used for outdoor applications and other spaces in need of tough, versatile parts. With more than half a decade of experience in providing custom rubber solutions for businesses, Timco Rubber can work with you to provide the right EPDM parts for your applications.
What is EPDM: A Versatile, Cost-Effective Rubber Part Solution
When you need a rubber material that offers excellent resistances to weather, heat, and other factors without breaking the bank, EPDM grommets, gaskets, tubing, and other parts may be the answer you need.
EPDM – also known as ethylene propylene diene monomer – is an extremely versatile material used in a variety of applications, from automotive products to HVAC parts. This type of rubber also acts as a less expensive alternative to silicone, as it can endure weather conditions, abrasion, and other challenges for long periods of time with proper use. As such, EPDM can save you time and money on a wide range of applications.

EPDM Benefits and Advantages
- Resistance to UV exposure, ozone, aging, weathering, and many chemicals – great for outdoor applications
- Stability in high and low temperatures – a general purpose EPDM material can be used in an environment where the temperature range is from -20⁰F to +350⁰F (-29⁰C to 177⁰C).
- Low electrical conductivity
- Steam and water resistant
- Can be fabricated in a variety of ways, which includes custom molded and extruded parts
- Long-term part lifespan allows for fewer replacement parts, saving money in the long run
