GYLON EPIX™ is a family of gaskets that effectively seals a broader range of applications and is more forgiving during the installation process. It allows the end user to save valuable turn-around time, reduce re-work, and lower costs, helping them to finish ahead of schedule and under budget.
GYLON EPIX™ features a hexagonal surface profile that provides the torque retention and blowout resistance of a thin gasket and the conformability of a thicker gasket. GYLON EPIX® Style 3500 is a high performance, silica filled PTFE gasket sheet material designed for use with strong acids, solvents, hydrocarbons, and other aggressive media. GYLON EPIX® Style 3500 withstands a wide range of chemicals for extended service in a wide variety of applications.

BACKGROUND ON APPLICATION
Expanded PTFE and 1/8” thick silica filled PTFE were formerly used to seal large diameter manway covers on FRP storage tanks and HCl absorber columns.
. To seal the crazed surface RTV or doping agent is used on the surface prior to gasket installation. After gasket installation the joint and surface treatment are checked for tightness with a pneumatic air test.
OPERATING CONDITIONS
- Temperature - 180°F (82°C)
- Media - hydrochloric gas, organic vapors and brine service
SOLUTION AND BENEFITS
After inspection and treatment of the crazed flanges, Garlock recommended installation of GYLON EPIX® 3500 which is designed for use with strong acids and aggressive media. Additionally, the raised profile improves sealability in low load applications such as FRP flanges. GYLON EPIX® 3500 has been successfully in service for over 18 months with no signs of leakage.
