Gasket Seals and Rubber Seals for Windows

EPDM rubber gaskets and window seals are ideal for sealing environments - like stationary windows - that aren’t exposed to oils, gasoline, kerosene, or concentrated acids. These locking gasket window seals provide excellent resistance to the following:

  • • Ozone
  • • Sunlight
  • • Severe weather conditions
  • • Oxygen
  • • Acids
  • • Aging

With outstanding color stability, odor-free characteristics, and high heat resistance, windshield gasket seals can be used in a wide range of industries and applications.

What Is the Difference Between a Seal and a Gasket?

A gasket, also called a gasket seal, is often used in static applications to prevent leakages, while seals are commonly used in active applications to prevent leaks between moving parts. Trim-Lok’s gasket seals are ideal for stationary windows. Learn more about this application below.

Window Seal Applications

Perhaps the most common application for EPDM rubber window seals is weather-stripping, particularly between a stationary window and body panel. Due to its ability to resist the elements, very high temperatures, and very low temperatures, our rubber window gaskets are typically used to seal and lock glass or Plexiglas windows into place on metal or fiberglass body on doors, cars, and trucks of all sizes.

Please note: EPDM rubber window gaskets have poor resistance to fuels and oils and should not be used in such applications.

Why EPDM Rubber for Window Seals?

Although window gaskets can be made from a variety of different materials, EPDM rubber gaskets are one of the most common types. 

Due to their sheer versatility, our gasket seals can be used in playgrounds, safety equipment, cold-room doors, medical devices, and heavy-duty and semi-truck “peeper” windows. The industrial and aerospace industries also favor gasket seals to dependably seal windows into place. Whether your project calls for a single prototype or large production runs, we provide you with EPDM window gaskets that meet or exceed your expectations.
