D-Profile Sponge Rubber Seals

D-Profile Sponge Rubber Seals

D-Shaped Rubber Seal

Trim-Lok’s popular D-shaped rubber seals are available in a variety of specially designed shapes, with several height and width variations. Since each product is made from a custom formulated EPDM sponge rubber compound, they’ll provide excellent resistance to water absorption, ozone, sunlight aging, low temperature, and compression set. With a general temperature rating of -20°F to +158°F, our EPDM rubber foam seals are ideal for numerous applications.

D-Shaped Rubber Seal Features and Applications

Our D-shaped rubber seals are made from a durable EPDM foam rubber compound, with custom designs available. Our bulk manufacturing facility allows us to provide rubber extrusion at the lowest prices available on the market. Whether you’d like to drown out noise, eliminate vibration, or protect your vehicle or home from the elements, our D-seals are the perfect solution. With an assortment of sizes and models, we can help you find the right d-shaped weather seal for any job.

Fitting Your D-Shaped Rubber Seal

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 rubber and substrate. HT tape has low initial tack for easy repositioning during installation, and needs at least 72 hours of cure time before it comes to full bond strength. 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.
