GYLON® 3540 Microcellular PTFE Gaskets
Microcellular PTFE Gasketing for Glass-lined Equipment.
The GYLON® Style 3540 gasket is a highly compressible, microcelluar PTFE gasketing material designed to compress and conform to irregular or damaged surfaces, making it suitable for flanges that generate lower compressive stresses, such lined flanges and equipment.
Suitable for many non-metallic flanges*, Strong caustics, Strong acids, Hydrocarbons, Chlorine, Cryogenics, Glass-lined equipment.
*For flat face flanges, a minimum compressive stress of 1,500 psi is recommended on the contacted gasket area for 150 psig liquid service. Consult with the flange manufacturer to confirm that adequate compressive stress is available.
