The originator of contained O-Ring Sealing Fasteners, UNISEAL® offers over 65 years of experience solving pressure, vapor and moisture problems in assembly application of screws, bolts and rivets.

Designed and manufactured with an O-Ring groove beneath the head of the fastener, UNISEAL® screws control the level of O-Ring compression after installation making air and liquid sealed tight. By providing a solid seal there is no need for additional torque.

Use UNISEAL® in any application where you need to eliminate leakage from internal or external pressure. What’s more, UNISEAL® fasteners are reusable.

By preventing moisture and other contaminants from entering your equipment, UNISEAL® is the most effective way to seal and fasten – no matter the application.
