PTFE Gaskets
PTFE is a sealing material. Supplied in the form of a highly conformable, flexible strip, it is ideal for use in applications involving standard & nonstandard flanges. This material offers both versatility and convenience and is therefore often used as a backup sealing option in situations where conventional gaskets are not immediately available. E-PTFE has outstanding chemical resistance and is inherently clean, making the product particularly suitable for sealing against media or in situations where feedstock contamination may be of concern.
MOC Types : E-PTFE & Virgin PTFE
Graphite Gaskets
The Graphite range of sheet sealing materials is manufactured from high purity exfoliated graphite flake, and is available with or without a reinforcing metallic core. Graphite laminates are particularly suited for applications involving moderately high temperatures and pressures in a wide range of media. They are widely used in demanding industrial applications and in the petrochemical/refining industries. Because these products do not contain any rubber or polymeric binders they have the highest levels of stress retention, ensuring that gasket stress applied during assembly is maintained during service. Graphite based products are resistant to most industrial chemicals but susceptible to attack by oxidizing agents such as nitric acid.
MOC Types : Industrial Grade & Nuclear Grade
Rubber Gaskets
Rubber gasket materials offer a low cost sealing solution for applications where the additional strength offered by Composite materials with fibre reinforcements such as aramid, glass or carbon is not a requirement. Rubber materials are often used in low temperature and low pressure applications.
MOC Types : EPDM, Nitrile, Viton, Neoprene, Butyl & Natural Rubber
Semi-Metallic
Spiral Wound Gasket
A spiral wound gasket may include a centering ring, an inner ring or both. The outer centering ring guides / enters the gasket within the flange and acts as a compression limit, while the inner ring provides additional radial strength prevents from blow out force. The inner ring also reduces flange erosion and protects the sealing element. Resilience and strength make spiral wound gaskets an ideal choice under a variety of conditions and applications.

Jacketed Gasket
Metal Jacketed Gaskets, as the name suggests, consist of a metallic outer shell with either metallic or non-metallic compressed fibre 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.
Metal Jacketed Gaskets 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 smooth flange surface finishes, high bolt loads, and flange flatness in order to seal effectively.

Tanged Insert Gaskets
Tanged Insert Gaskets (Metal Reinforced Gasket) is a laminated gasket consisting of a tanged metal core, covered with soft conformable sealing materials on each face of the core. While the solid metal core prevents gasket blowout, it provides strength and rigidity when compare to soft cut Gaskets and the soft facings provide for an exceptional seal.
