GRINNELL Gasket Seal
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.
