This large sponge D seal is 39mm by 19mm and supplied by the linear metre. It is manufactured from a closed cell sponge which does not absorb water so is suitable for making watertight seals on hatches, lockers, enclosures, doors, and cabinets. The large hollow void allows for the D section to easily compress providing a long-term watertight sealing solution.
The base of this section can be bonded onto most clean flat surfaces such as metal, wood and plastic. We recommend using a good quality contact adhesive such as S136 or A262 (available from our website).
We manufacture this product from high quality expanded EPDM which is a compressible material suitable for a wide range of applications. When compressed to approximately 30%, this section will create a good long-term watertight seal without risk of compression set. This material has a good modular resistance to most substances including most chemicals, UV, air and ozone but is not recommended in environments which may come into contact with oil or fuel. EPDM has an operating temperature range between -40°C to +120°C.
