Gylon® Gaskets

A range of punched, cut, extruded, sheet and fabricated products.

What is a Gylon® Gasket?

Gylon gasketsA Gylon® gasket is a highly compressible adapted variation of a PTFE gasket. Gylon® gaskets are highly resistant to chemicals whilst still retaining all the advantageous properties of PTFE. However, Gylon® gaskets reduce the amount of flow and creep problems that are traditionally associated with PTFE products.

What is Gylon® Gasket material?

What are Gylon® Gaskets made of? Gylon® is a PTFE material, available in a range of grades for specific applications and/or industries. With outstanding chemical resistance for harsh environments, and an excellent temperature range, the Garlock branded Gylon® material also addresses the issues of creep and cold flow that would usually be seen with virgin materials and those not manufactured using this unique Garlock process. The unique proprietary manufacturing process ensures a homogenous material which is consistent across the sheet, and enables the added fillers that confer specific properties to be distributed evenly, increasing the tensile properties and providing a more consistent product.

Gylon® Gasket Specific Materials

There are a range of different Gylon® Gasket materials to choose from. Some of the more specific Gylon® Gasket materials include:

Gylon® Style 3500

Fawn Gylon®; PTFE with a silica filler, offering improved performance over standard PTFE materials as well as reducing creep relaxation and cold flow. Suitable for use with strong acids (not hydrofluoric), solvents, hydrocarbons, water, steam, chlorine, cryogenics. -268°c to +260°c, up to 1200 PSI.

Gylon® Style 3504

Gylon® blue gaskets; PTFE with aluminosilicate microspheres, suitable for use with moderate concentrations of acids and some caustics, hydrocarbons, solvents, water, refrigerants, cryogenics and hydrogen peroxide. -268°c to +260°c, up to 800 PSI.

Gylon® Style 3505

Gylon® blue gaskets; PTFE with aluminosilicate microspheres as above but NSF61 approved for oxygen service. Recommended for use with potable drinking water, hydrocarbons, solvents, moderate concentrations of acids and some caustics, refrigerants, hydrogen peroxide. -268°c to +260°c, up to 800 PSI.

Gylon® Style 3510

Off-white Gylon®; PTFE with a barium sulphate filler, developed for its excellent resistance to high concentrations of caustics which are commonly found in the pulp and paper industry. Developed for use with strong caustics, moderate acids, chlorine, gases, water, steam, hydrocarbons, cryogenics and aluminium fluoride. -268°c to +260°c, up to 1200 PSI.

Gylon® Style 3545

Microcellular PTFE outer layers with a rigid PTFE core. Conforms to FDA regulations. Highly compressible so that it seals under low bolt load and is therefore suitable for non-metallic flanges, compressible layers also conform to surface irregularities, whilst the rigid PTFE reduces cold flow and creep. Suitable for use with strong caustics, strong acids, hydrocarbons, chlorine and cryogenics. -268°c to +260°c, up to 1200 PSI.

Gylon® Style 3565

Envelon® – PTFE gasketing with aluminosilicate microsphere filler; a soft, deformable exterior conforms to surface irregularities whilst the stable blue core improves cold flow resistance. A low bolt-load requirement means that a tight seal can be achieved on glass-lined or imperfect flanges, and the direct sintering of Gylon® prevents leaks and adhesive contamination. Suitable for use with moderate concentrations of acids and caustics, hydrocarbons, solvents, cryogenics and glass-lined equipment. -268°c to +260°c, up to 800 PSI.
