What is Linebacker-seal Flange Isolation Gasket Kit?

Linebacker-seal flange isolation gasket kit uses a rectangular sealing element, in combination with a unique groove design to effectively seal and isolate flanges of all types. With the unique rectangular quad ring design, elastic memory is provided for elastomers not normally associated with this characteristic. Linebacker-seal flange isolation gasket kit provides excellent temperature and chemical range compatibility.

Features and Benefits

Linebacker-seal flange isolation gasket kit can eliminate flange leaks, guards against blowouts and matches gasket materials to service conditions. The type gasket is usable with virtually any type of flange, Lowest possible clamp and compressive load, Linebacker-seal flange isolation gasket kit is both a positive seal and a superior insulator.

Pressure Ratings

All ANSI rated flanges are up to 900#. Maximum hydro test pressure is 3350 psi and maximum operating pressure is 2,225psi. The Linebacker-seal flange isolation gasket kit also performs well in vacuum service.

How The Seal Functions

Before Tightening

The flange faces come into contact with the sealing elements, which extend slightly above the surface of the retainer. As the flange is tightened the sealing elements are compressed and move sideways into the inclined portion of the groove, developing a high unit pressure against the flange faces.

Before Tightening

After Tightening

The flange faces have come into firm contact with the retainer, thus encapsulating the sealing elements within grooves. At the same time, the unique seal configuration of Linebacker-seal flange isolation gasket kit provides elastic memory for elastomers not normally associated with this characteristic – resulting in a simple flat gasket with extremely high loading and self energizing characteristics without adverse cold flow problems.
