D-Profile Round Rubber Seals

D-shaped round rubber seal with adhesive-backed rubber strips

Round Rubber Seals and D-Shaped Weather Stripping

Trim-Lok’s popular D-shaped round rubber seals are available in a variety of specially designed height and width variations. Since each product is made from a custom-formulated EPDM sponge rubber compound, they provide excellent resistance to water absorption, ozone, sunlight aging, low temperature, and compression set.

D-Shaped Round Rubber Seal Features and Applications

With a general temperature rating of -20°F to +158°F, our EPDM rubber foam seals are ideal for numerous applications. Our bulk manufacturing facility allows us to provide rubber extrusion at the lowest prices available on the market. Rubber D-seals can help to:

  • • Drown out noise
  • • Eliminate vibration
  • • Protect your vehicle or home from the elements

With an assortment of sizes and models, we can help you find the right d-shaped weather stripping for any project or repair. Watch our video to learn how to install rubber seals on windows, doors and more.

Fit Options for Adhesive-Backed Rubber Strips

When fitting the D-shaped rubber seals or D-seal gaskets into your boat or car, choose from two adhesive options: BT tape or HT tape.

  • • BT tape is an acrylic, automotive-grade tape that creates a moisture barrier and airtight seal between the round rubber seal and a substrate.
  • • HT tape is an acrylic-based adhesive used to hold the rubber seal in place during installation; it may be used in some light-duty dynamic applications against a variety of substrates. It has low initial tack for easy repositioning during installation. It needs at least 72 hours of cure time before it achieves full bond strength.

Round Rubber Seals Serve Many Industries

Whether you need to seal out water, noise, vibration, dust or dirt—the possibilities are endless with our 3M D-shaped rubber seals. Trim-Lok rubber D-seals are ideal for the automotive and marine industries, manufacturing, garage doors, windows, and much more.
