Sealing Screws and Plugs
What is a sealing screw?
An ordinary screw lacks seal protection, allowing dirt, fluids, gases etc. to infiltrate and damage sensitive devices. Sealing screws provide bi-directional sealing protection to systems where screws are used, to protect them against dirt, chemicals, water or other contaminates, which (without the screw seal), may penetrate and damage or alternatively where gases and liquids may leak out.
The seal screws incorporate an O-ring underneath the screw, bolt etc which forms a sealant layer.
The seal provides bi-directional sealing.
Seal screw fasteners are designed and manufactured with a precision engineered groove beneath the head of the fastener. As the fastener is tightened, the O-ring is compressed, squeezing the O-ring between the groove and mating surface to complete the seal.
