Product Information

EPDM Sponge Door Seal 15mm x 18mm

Our EPDM sponge door seal 15mm x 18mm is a highly durable sealing solution. It is suitable for use as an airtight as well as a watertight seal on a wide range of door types and materials. Over a long period of use the seals can deteriorate, which reduces the sealing capabilities. This enables wind and water to enter through the gap between the door and the frame. We design and manufacture this particular door seal using high-quality materials to ensure that it can withstand heavy use over a long period of time.

This door seal has a base width of 14mm and a maximum height of 18mm. These specific sizes enable you to install our product on a wide variety of different door sizes while also ensuring the maximum sealing properties possible. The sponge sealing section of this product is hollow in design as it allows our product to compress under pressure and fill any irregularities on the surface of the door. Our door seal also comes with an adhesive strip to allow for a fast as well as secure installation solution.

We manufacture this door seal from two different rubber materials to give our product benefits from both. We make the base from a solid EPDM rubber material, which offers excellent resistance to extreme hot as well as cold temperatures. In order to ensure the best sealing properties possible, we make the top section from a sponge EPDM material. This material offers excellent air and watertight properties. It is also resistant to a wide range of chemicals which ensures that our seal requires little to no maintenance.

We have a wide selection of sponge extrusions in a variety of different shapes and sizes to fit any application. Click here to view our full sponge profile section.
