Non Metallic Gaskets

Compressed Non-asbestos Gaskets

Compressed Non-asbestos Gaskets are sealing devices designed to create a tight, leak-proof connection between two flange surfaces in industrial applications. Compressed Non-asbestos Gaskets are a blend of fibers and rubber materials bound together. They are designed to create a tight seal between two flange surfaces in industrial applications.
A wide range of compressed sheet materials are available in a variety of fiber and rubber combinations that are chosen for their compatibility with specific chemicals and resistance to high temperatures. Sheet gaskets are designed with the compressibility necessary to fill in the voids of the flange surfaces and the resiliency to maintain the seal with temperature and pressure fluctuation.

PTFE Gaskets

PTFE (Polytetrafluoroethylene) has emerged as the common thermoplastic gasket material. PTFE's outstanding properties include resistance to temperature extremes from cryogenic to 500°F (260°C). PTFE is highly resistant to chemicals, solvents, caustics, and acids except for free fluorine and alkali metals. It has a very low surface energy and does not adhere to the flanges. PTFE gaskets can be supplied in a variety of forms; either as virgin or reprocessed material, and also with a variety of filler material.

Graphite Gaskets

Graphite gaskets are used to seal joints in adverse conditions. There are several types of graphite gaskets including: flexible, reinforced, tape, spiral, foil, and ring gaskets. These types of graphite gaskets all have properties in common including chemical inertness, high strength, resistance to creep, and low coefficient of friction.
Applications for graphite gaskets include pipework, heat exchangers, automotive engines, and petrochemical processing plants.
By using a graphite gasket, the gap in a joint can be more effectively sealed, which can increase the performance of the system. Graphite gaskets are desirable over other gaskets due to their longevity.

Rubber Gaskets

Rubber gaskets play a crucial role in sealing the interfaces between parts. Their primary purpose is to prevent leakage, ensuring airtight or watertight seals between two surfaces. These flexible components are commonly made from elastomers like neoprene, EPDM, silicone, or nitrile. Each material offers unique properties.

Cork Gaskets

The distinctive qualities of cork gaskets, which are well known for their flexibility and durability, make them widely used in a variety of industries. Cork gaskets are highly compressible and work well to seal joints, stopping leaks in commercial, residential, and automobile environments. They are durable in harsh conditions because of their innate resistance to chemicals and oil.

Mica Gaskets

Mica gasket material is exceptional in its resistance to high heat. At temperatures over 900 F, the ideal sealing material flexible graphite cannot be used.
Flexible graphite will coke at those elevated temperatures when oxygen is present, whereas mica gasket material will not (900 - 1850 F). Mica gaskets can be
very effective in sealing those high-temperature critical applications without failing due to the presence of oxygen.
