Semi-Metallic Gaskets

Semi-Metallic gaskets are designed to feature soft, pliable sealing materials - which enhance the tightness of the assembly with lower overall load requirements when compared to full metallic gaskets. They are most popular due to this configuration, and are available in a wide variety of styles and sizes. They are resilient and, as a consequence, can compensate somewhat for flange movement that may occur due to temperature gradients, variations of pressure and vibration. Please contact JLM Supply for additional information.

Spiral Wound Gaskets

Lamons Spiral Wound gaskets are available in a variety of styles to suit the particular flange facing being utilized on the flanges.

Kammprofile Gaskets

Lamons Kammprofile gaskets are recognized as a problem solver for heat exchangers, large vessels, and equipment that experience excessive movement due to thermal expansion. The Kammpro provides one of the tightest seals combined with superior load bearing characteristics.

Corrugated Metal Gaskets

The Lamons CMG family of products are considered the standard in respect to corrugated metal gasket technology; an excellent choice for 150 and 300 class ASME flanges where available bolt loading is minimal.

Metal Jacketed Gaskets

Metallic gaskets can come in different styles like; double jacket, single jacket, or solid metal. Soft compressible filler material can be flexible graphite, PTFE, or non-asbestos compressed sheet type. The design of a metal jacketed gasket also may require different shapes and the styles mentioned above can be made to a variety.

High Temperature Gaskets

Lamons high temperature gaskets represent the ultimate solution for industrial bolted joints that are exposed to extreme temperature. The HTG design combines the superior sealing performance of a premium oxidation inhibited grade flexible graphite with an exceptional oxidation barrier in mica/phyllosilicate. The combination of these two sealing materials allows the user to eliminate the effects of oxidation at extreme temperatures.


The Lamons CorruKammâ„¢ resembles a typical kammprofiled sealing element in that it utilizes a heavy substrate capable of extreme load bearing properties. The dramatic feature that this design incorporates is a precisely located corrugated pattern which greatly enhances the ability to deflect and compress under load. This creates a scenario in which the gasket will be more forgiving where perfect alignment and parallelism do not exist.

A "Soft Gasket" material is a term used when referring to a gasket material that is easily compressed under a low bolt load. This term has been used to distinguish the difference from a metallic gasket. A soft gasket material can be selected from a large variety of rubbers and compressed non-asbestos sheet products. As part of Lamons strategy to offer customers a wider range of products, we are pleased to supply the following soft gasket materials:
