What are kammprofile gaskets? Kammprofile Gaskets are composite gaskets, which utilizes a serrated metal core with a soft material. The metal core is machined on each contact face with concentric serrations which provide high pressure areas, ensuring that the soft coating flows into any imperfections in the flange even at relatively low bolt loads. The result is a gasket which combines the benefits of soft cut materials with the advantages or sealing integrity associated with metallic gaskets. Expanded graphite is the most common facing material used for Kammprofile Gaskets. However, other materials can be used, such as PTFE for chemically aggressive duties or mica for high temperature duties, etc. Types of Kammprofile Gaskets Basic style kammprofile gaskets * This type kammprofile gasket for tongue and groove flanges * Gasket without inner and outer rings * Concentrically grooved profile on both sizes and covered with soft material layers Kammprofile gasket with integral outer ring * Kammprofile gasket with machined centering ring * The metallic core is made with a concentrically grooved profile on both sides and a machined centering ring * Gasket with soft sealing layer both sealing surface Kammprofile gasket with loose outer ring * The metallic core is made with concentrically grooved profiling on both sides * A notch is turned on the outer circumference of the core in which a loose centering ring * With soft sealing layer in both sides Material of construction Carbon steel, stainless steel, 321, 347, monel 400, inconel, incoloy, nickel, titanium, hastelloy, copper Coating materials: Graphite, PTFE etc. Specifications Products are manufactured in accordance with all relevant gasket standards to suit flange designations: ASME B16.5, BS1560, ASME B16.47, BS EN1092, DIN, JIS and NF.

lens ring joint gasket is a line contact seal for use in high pressure piping systems and in pressure vessel heads. The lens cross section is a spherical gasket surface and requires special machining on the flanges. Since the contact area is very small and gasket seating pressures are very high, the gaskets will seat with a small bolt load. Lens ring joint gasket is manufactured in accordance with DIN 2696, provide the engineer with a high integrity, high pressure and temperature seal for special applications. Lens rings have a spherical surface and are suitable for use with conical flange faces. So other styles are available on request. Lens Ring Joint Gasket * Lens ring joint used in higher pressure then 3,000 lbs. * These gaskets had been used on pipe flanges in synthesizing line. Prime Features As the standard, the gasket material should be softer than the flange material, thus ensuring that the applied compressive load leads to the elastic and plastic deformation of the lens ring and not the flange sealing face As with all metallic joints, the re-use of lens rings is not recommended.

Solid copper gasket to make a leak tight UHV seal between two conflat flanges. Oxygen free high conductivity (OFHC) copper is normally used as this sealing material as it is very clean, can easily be formed to shape, has a wide temperature range, and has a low outgassing rate. “OFHC” copper gaskets are not always needed for all requirements, we have a range of several different types of gasket materials can be used for most of the general UHV applications.

Copper head gaskets are designed for use in all high performance applications that require an extra measure of sealing or use very high compression. Whether the application is Top Fuel, Circle Track or even Street, there is no better sealing or more durable gasket material than solid copper. Precision CNC machined from a sheet of solid copper, these copper head gaskets offer precise bore and stud hole alignment for a drop-on fit. Being solid, they will not compress so there is no need to re-torque and being solid they can not blowout. Copper head gaskets may cost more initially, but the improved sealing and reusability make these well worth the investment in the long run. Each set contains two ready-to-use “dead soft” copper head gaskets. Copper Exhaust Gasket * For Turbo, nitrous high compression, blown applications * Precision CNC machined from a sheet of solid copper * The gaskets are reusable with proper handing and installation
