Welcome to Exactseal, your trusted manufacturer of high-quality O-rings. One of our specialties is the production of EPDM O-ring.

EPDM, or Ethylene Propylene Diene Monomer, is a type of synthetic rubber known for its outstanding mechanical properties. It’s highly durable and resistant to numerous environmental factors. This makes EPDM O-rings incredibly versatile, and suitable for a broad spectrum of applications across various industries.

Our EPDM O-rings are designed to withstand extreme temperatures, from as low as -60°F/-51°C to up to 300°F/150°C. They are also resistant to hot water and steam1. This makes them ideal for applications that involve extreme temperatures, such as in the automotive and aerospace industries.

In the automotive industry, our EPDM O-rings are used as sealing gaskets, fuel fittings, and hose connections. In the aerospace industry, they are valued for their reliable resistance to chemicals and their ability to withstand extreme temperatures.

However the applications of our EPDM O-ring extend beyond these industries. They are also used in the food industry, medical devices, household appliances, and water and wastewater systems. Their superior properties make them one of the most popular choices for these industries.

At Exactseal, we understand that each application has unique requirements. That’s why we offer custom configurations for our EPDM O-rings. We can provide custom sizes, shapes, and compositions to meet the specific needs of any application1.
