Product: Metal Jacketed Gaskets
Metal Jacketed Gaskets, as the name suggests, comprise of a metallic outer shell with either a metallic
or non-metallic asbestos free filler. The filler material gives the gasket resilience, while the metal jacket
protects the filler and resists pressures, temperatures and corrosion.
A wide range of materials are available to suit specific temperature and corrosive conditions.
Metallic:
Aluminum
Brass
Copper
Soft Iron
Stainless Steel
MonelÆÊ
NickelÆÊ
InconelÆÊ
(Other materials on request)
Non-Metallic:
Non-asbestos Millboard
PTFE
FlexicarbÆÊ
CeramicÆÊ
Metal Jacketed Gaskets are manufactured using hand made techniques, and are available in a wide
range of sizes and configurations. They are traditionally used for heat exchanger applications, pumps,
and valves, however the resilience and recovery properties of these gaskets are limited. Metal Jacketed
Gaskets require exacting conditions of flange surface finish, high bolt loads, and flange flatness in order
to effect a seal.
SINGLE JACKETED GASKETS
The filler material is enclosed in a metal jacket which covers the inside and outside diameter of the
gasket. Style 120 has one of its contact surfaces covered and is ideally suited for comparatively narrow
flange widths in circular and non-circular configurations. Style 124 is an overlapped Single Jacketed
Gasket, where the filler is completely enclosed on the inside and outside diameters and on both contact
surfaces. Style 124 is more suited for high temperature applications of narrow flange widths.
Typical low pressure applications include boilers, compressors, pumps, and diesel and gasoline engines.
Style 120 is not recommended for standard pipe flanges. Minimum flange width 6.4mm (1/4.). Nominal
gasket thickness 3.2mm (1/8.).
