D shape extrusions are designed to compress under pressure and create a tight seal.
The flat side mounts easily to most surfaces and the round top will compress to fill smooth or uneven gaps.
Half rounds will seal out contaminants and cushion joints to reduce rattling and vibration.
Available in a variety of rubber compounds depending on your application including Viton, Silicone, Fluorosilicone, Neoprene, EPDM, Hypalon, Butyl, Nitrile, SBR and Natural rubber.
