NEW! GYLON EPIX PTFE Gasketing from Garlock

GYLON EPIX Style 3504The Perfect Solution for Imperfect Flanges

The all-new patented GYLON EPIX looks like no other gasket because it’s not like any other gasket. Its patented hexagonal surface profile combines best-in-class torque retention with exceptional conformability, allowing you to use a single thickness for nearly any application—even worn or pitted flanges.

Why Gaskets Fail

Incorrect bolt load accounts for 83% of gasket failures. GYLON EPIX helps overcome these challenges, so that even when bolt load isn’t perfect, performance isn’t compromised.

Product Highlights

Inventory Simplification

One universal thickness—3/32″ (2.4mm)—eliminates the need to stock a variety of material thickness with different stress requirements.

Improved Load Retention

The hexagonal surface profile provides the torque retention and blowout resistance of a thin gasket and the conformability of a thicker gasket.

Trusted Materials

Made from the same materials as standard GYLON products, it eliminates the need for most customers to qualify the new GYLON EPIX products.
