PTFE with Barium Sulfate Gasketing for High Pressure Applications
GYLON® Style HP 3561 is high performance, barium sulfate filled PTFE gasketing material that contains a perforated 316L stainless steel insert for improved pressure resistance (can withstand up to 2,500 PSI).
FEATURES and BENEFITS
- Tight seal
- Perforated stainless steel core increases resistance to pressure fluctuations and thermal cycling
- GYLON® offers superior cold flow and creep resistance, eliminating the need for frequent retorquing
- Chemical resistance
- Seals aggressive chemicals in hostile environments where safety or blowout resistance is crucial*
- Will not support flame
- Will not support bacterial growth
*Consult Garlock® Applications Engineering when using flanges in pressure classes above 300lbs.
