GYLON® Style 3545

GYLON® 3545 designed to compress and conform to irregularities, especially on warped or scratched flanges. The compressible layers make it suitable for surfaces that generate lower compressive stresses, such and glass-lined flanges and low bolt load equipment.

GYLON® Style 3545 is a highly compressible microcellular PTFE with a rigid PTFE core for improved handlability. The rigid PTFE core facilitates installation, especially on large diameter flanges and hard-to-reach areas and also reduces cold flow and creep.

GYLON® Style 3545 reduces product loss and emissions with a reduced creep relaxation and excellent bolt torque retention. It withstands a wide range of chemicals in a wide variety of applications. It also will not support flames or bacterial growth.

Applications: Strong caustics, Strong acids, Hydrocarbons, Chlorine, Cryogenics, Glass-lined equipment, Low bolt load applications*

*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.
