GRINNELL Gasket Types
Tech Data Sheet: G610
Pressure responsive gaskets are offered in a variety of types . Although they each serve a specific function they all utilise the same sealing design .
The GRINNELL gasket is designed to provide a three-way sealing action .
(1) Installation of the gasket over the outside sealing surface of the pipe compresses the lip seal and forms the initial seal .
(2) The installation of the housing segments around the gasket and into the pipe groove properly positions the gasket . Tightening of the housing segments forms the gasket to the inside of the housing and compresses
it around the pipe-sealing surface thus increasing the gasket’s sealing against the pipe .
(3) The introduction of the system pressure energises the pressure responsive seal of the gasket and further enhances the sealing action .
First Seal
C-shaped rubber gasket seals on pipe ends .
Second Seal
The housings compress the gasket to increase the sealing capacity .
Third Seal
The system pressure or vacuum will then maximise the leak-tight seal .
