Severe Service Gasketing
Garlock® GYLON® gasketing is a family of severe service PTFE gasketing materials manufactured using a proprietary process that imparts unique physical properties that are not obtainable through conventional manufacturing methods.
The innovative GYLON® manufacturing process reorients the PTFE and fillers in a way that increases the material’s tensile properties and decreases the creep relaxation problems that usually plague PTFE products. In addition, the mixing process creates a homogenous material with consistent, superior physical properties that, unlike inferior skived PTFE sheet gaskets, do not fluctuate from one side of the sheet to another. Plus, our patented thermal bonding process allows us to fabricate gaskets of nearly any size.
Designed for severe chemical service, GYLON® gasket materials are color-coded for easy identification and provide superior sealability to reduce process and media loss and fugitive emissions. They also reduce creep and cold flow characteristics.
PTFE with Silica Filler Gasketing
The GYLON® Style 3500 is a high performance, silica filled PTFE sheet material designed for use with strong acids, solvents, hydrocarbons, and other aggressive media.
PTFE with Aluminosilicate Microspheres Gasketing
Made of PTFE with aluminosilicate microspheres, the GYLON Style 3504 gasket is designed for acids, caustic hydrocarbons, refrigerants and more. Read more about this product below, and contact Gallagher Fluid Seals if you have any additional questions.
NSF 61 Approved PTFE with Aluminosilicate Microspheres Gasketing
The GYLON® Style 3505 PTFE gasket is aluminosilicate microsphere filled PTFE, ideal for use in oxygen service. This high-performance gasketing material is also NSF 61-approved for use in potable water service. It is a trusted choice for water lines where electrical isolation properties are a necessity. Contact the sealing experts at Gallagher Fluid Seals to learn more about this gasketing material.
PTFE with Barium Sulfate Filler Gasketing Material
The GYLON® Style 3510 is a high performance, barium sulfate filled PTFE gasketing material designed for use in powerful caustics and toxic chemicals where initiating and maintaining an extremely tight seal is crucial, including chlorine, ammonia and phosgene. When it comes to monomer services, it delivers exceptional levels of performance. Read more about this product below, and contact Gallagher Fluid Seals to learn more about the GYLON® Style 3510.
PTFE with Graphite Filler Gasketing Material
A high-performance graphite-filled PTFE gasketing material, the GYLON® Style 3530 is designed to withstand volatile hazardous air pollutants and high concentrations of hydrofluoric acid.
