Product Details


The semi-metallic gasket joint is an economical sealing option where sealing faces are narrow, this type of gasket makes it a good option for heat exchanger jointing. The metal jacket provides good gasket stability and blow-out resistance. Selecting the right type of metal will provide a suitable resistance to a wide range of chemical media.

Welded Construction

Gaskets with bar configurations are securely welded into the ring by our experienced engineers. The media is retained by the primary seal at the inner diameter of the gasket. The primary seal therefore maintains its function and provides a seal of higher integrity.

One-Piece construction

Gaskets are fabricated from a single sheet of material.

Pass bar partitions are fabricated in one piece construction where they intersect with the outside ring and where bars intersect or change direction within the ring. Should leakage occur, the media would flow along the length of the pass bar arrangements and then flow to the outer diameter and retention is maintained by the secondary seal.
