Specification for D-Shaped Profile Rubber Seals
Description Rubber seals come in a variety of specially designed shapes and are made from a variety of custom-formulated rubber compounds. Most D-shaped weatherstripping is made of EPDM (ethylene propylene diene monomer) sponge rubber, which is custom formulated and compounded to provide excellent resistance to water absorption, sunlight aging, weatherproof sealing, etc. Installing D-shaped rubber weatherstripping creates a waterproof seal, reduces noise, eliminates vibration, and protects your vehicle doors, windows, or applications from moisture and debris.

ZYXrubber is a leading manufacturer and supplier of extruded D-shaped rubber seals for weather seal, including weatherstrips, door seals, D Profile Sponge Rubber Seals, 3m D-shaped rubber seals, D-Shaped Foam Rubber Seals, Adhesive-backed D-shaped seals, and a variety of specially designed shapes and dimensions of D rubber extrusions. Our EPDM rubber seals boast a versatile temperature rating, ranging from -40°F to +250°F, making them the perfect choice for a wide array of applications across various industries. Whether you require a reliable sealing solution for harsh environments, extreme conditions, or anything in between, these seals are engineered to excel.

Certifications and Compliance: Depending on the application industry and regulations, we can offer D-shaped rubber seals that meet specific certifications and compliance standards, such as FDA, RoHS, or REACH. 

Common Types of Adhesive-Backed D-Shaped Gaskets
Many D-shaped seals come with self-adhesive backings for easy "peel-and-stick" installation. Common types include:
  • Standard Pressure-Sensitive Adhesive (PSA): Good for static applications where the seal is compressed between two stationary objects.
  • High Tack PSA: Bonds more quickly and offers better adhesion to some plastics.
  • 3M Bonded Tape System (BT): Creates a strong, moisture-proof, and airtight seal with high peel and shear resistance, suitable for high-stress applications. Requires 72 hours to reach full strength.

Industries and Solutions for Half-Round Rubber Seals
