Metal Jacketed Gaskets

Masterpac metal jacketed gaskets are normally supplied with a high temperature or non-asbestos filler. The standard filler is normally sufficient for applications up to 500°C. Standard metals used to make jacketed gaskets ranging from aluminum, copper, the various brasses, soft steel, nickel, Monel®, Inconel®, and stainless steel types 304, 316, 321, 347.

Double Jacketed Gaskets (DBJ)

Double Jacketed Gaskets are used on boiler and heat exchanger applications when ample bolting is available to correctly seat the gasket. They are designed for high pressure and temperature applications up to and inclusive of Class 900. The temperature limitation of the gasket is dictated by the combination of metallic and non-metallic materials used in its construction. 

The standard Double Jacketed Gasket has good compressibility and resilience and is the most popular clad gasket manufactured. For Double Jacketed Corrugated, this style employs a corrugated jacket to increase resilience and suited for circular and non-circular application in widths of 3/8" and wider, it is an improvement over the standard Double Jacketed Gasket. If slight leakage should occur across the primary seal at the inner edge of the gasket, the concentric corrugations act as labyrinth seals.

Double Corrugated Metal Gaskets

Double jacketed corrugated gasket is an improvement on  a plain jacketed gasket in that the corrugations on the gasket will provide an additional labyrinth seals. It is also provides the advantage of reducing the contact area of the gasket, enhancing its compressive characteristics. Corrugated Gaskets are a versatile sealing element where the available bolt loads are low. Depending on the materials and construction these gaskets can be very resilient.

Single Jacketed Gaskets

This standard Single Jacketed Gasket has one of its contact surfaces covered and is ideally suited for comparatively narrow flange widths in circular and non-circular configurations but  it is not recommended for standard pipe flanges.

For Overlapped Single Jacketed Gasket, its construction of this gasket offers more filler protection than the standard single jacketed design. It is especially suitable for high temperature applications of narrow gasket widths. Typical low pressure applications include boilers, compressors, pumps, and diesel and gasoline engines.
