GYLON^® Gasketing Style 3545

FEATURES AND BENEFITS

Tight seal
Highly compressible PTFE outer layers seal under low bolt load
Compressible layers conform to irregularities, especially on warped, pitted, or scratched flanges
Rigid PTFE core reduces cold flow and creep
Withstands a wide range of chemicals
Can be cut from larger sheets, reducing inventory costs and expensive downtime
Rigid PTFE core facilitates installation, especially on large diameter flanges and hard-to-reach areas
Will not support flame
Will not support bacterial growth

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.

† When sealing uneven flanges, gasket must be four times thicker than maximum gap between flanges.
