The Flange Sealing Clamp is designed to seal off flange leakages. Depending on the pressure, the clamp can either be delivered as self-sealing unit or equipped with a sealant injection system. Sealing is obtained by compressed rubber seals, enveloping the leaking flange surface and if required, by injection of sealant.  Sealants are designed to react based on simple fluid dynamics, solidifying post-injection to provide the required sealing capability.
