A gasket with a metallic outer shell and either a
metallic or non-metallic compressed fiber filler is
Metal Jacketed Gasket where the filler material offers
resilience and metal jacket protects the filler and
resists pressure, temperature and corrosion.
Metal jacketed gaskets manufactured at Goodrich Gasket
are used as heat exchanger gaskets and also in pumps,
valves etc despite of their limited recovery and
resilience property. Gasket sealing is effective under
high bolt loads, smooth flange surface finish and flange
flatness.
The gasket materials used for its construction are:
Metallic category includes Soft iron, Carbon Steel,
Stainless Steel, Inconel, Monel, Nickel, Aluminum,
Brass, Copper etc. Non-Metallic category includes
compressed fiber millboard, PTFE, Tanged insert
graphite, Ceramic etc.
The types of metal jacketed gaskets Goodrich Gasket
offers are:
Single Jacketed Gaskets, Filler material enclosed in a
metal jacket, covering the inside & outside diameter
of gasket
