Kammprofile Gasket is processed by special equipment into concentric circle trough, which makes its sealing effect much more excellent than their common metallic plate gaskets. It is especially suitable for connects of Flange, Tubes, Caps of pressure containers and various Valves.

Metallic Ring Joint Gaskets are heavy duty, high pressure gaskets. Largely used in offshore petrochemical applications. They are precision engineered compounds designed to be used in conjunction with precision machined grooved flanges.

Teflon is principally used as a gasket material because of it's capability to remain unaffected by the majority of chemicals used in industry. It is also classified, in most cases, as a food grade material, making it acceptable to both medical and food production industries. There are three basic types of Teflon gasket materials. Virgin Teflon, Filled Teflon and Expanded Teflon.
Virgin Teflon is by far the least expensive of the three varieties, and is used in most general applications.
Filled Teflon is a gasket material with a virgin Teflon base to which a substance is added during manufacture to improve the sealing characteristics of Teflon. This "filler" usually is glass or graphite particles although ceramics has sometimes been used. The resulting gasket material is strong, yet highly compressible with very good, though not universal, chemical resistance.
Expanded Teflon is virgin Teflon to which a stress resistance has been added by means of molecular rearrangement during manufacture. This process ensures that the molecular chains from which the Teflon is constructed, do not arrange themselves into set patterns. This means that expanded Teflon possesses no structural weakness (grain) and expands and contracts equally in all directions. Because no additives are required, expanded Teflon also possesses the unique chemical resistance of virgin Teflon
A Spiral Wound Gasket is made of alternate plies of “ V “ preformed hoop and soft filler that are tightly and spirally wound together. The metal winding ground the entire inside and outside circumferences of the gaskets is spot welded. Normal practice is to reinforce the inside and outside diameters with several plies of the metal winding without filler being introduced. According to the need of the mating flanges, the gasket is provided – with an Outer Ring or Inner Ring or both Outer & Inner Rings.
The Outer Ring serves as a compression stop, Anti – Blowout device, which properly centers gaskets on the flange. The Inner Ring acts as a compression stop and is used to till the space between the flange bore and the gasket inside diameter to minimize turbulence of process fluids and erosion of flange face.
On rare occasions, applications for Spiral Wound Gaskets arise where it is necessary to spiral wound outer and or inner ring. The spiral wound outer or inner rings are used as reinforcement and are chosen in stead of a solid metal ring, because of lower costs or because of limited space when the use of a solid metal ring would be prohibited due to the difficulty in fabrication or usage.
