Garlock Gylon 3500 Flat Gasket – 1/4 Inch, 300LB, RF

The Garlock Gylon 3500 Flat Gasket is a high-performance sealing solution designed for industrial applications requiring chemical resistance and durability. Manufactured from PTFE reinforced with silica, this gasket provides excellent compressibility, resilience, and long-term leak-tight performance, even under fluctuating pressures and temperatures.

Compliant with ASME B16.20, the gasket is rated for 300LB flanges and comes in a thickness of 3.2mm. It is suitable for raised face (RF) flange connections and can withstand an extreme service temperature range from -268℃ to +260℃, making it ideal for both cryogenic and high-temperature processes.

This gasket is widely used in chemical, petrochemical, pharmaceutical, and food processing industries, where resistance to aggressive chemicals, steam, and high-purity media is critical. Its combination of PTFE’s chemical inertness and silica’s mechanical reinforcement ensures reliable sealing performance in demanding environments.
