Superlon® PTFE Gaskets
Superlon® gaskets are high-performance, non-porous sealing solutions engineered with pure virgin PTFE resin and reinforced with perforated 316 stainless steel (316 PERF metal). Designed for superior reliability in high-pressure, high-temperature, and chemically aggressive environments, Superlon® gaskets are ideal for critical industrial sealing applications.
Available in standard thicknesses of 1/8” and 3/32”, these gaskets deliver consistent, long-lasting performance across a wide range of industries including chemical processing, pharmaceuticals, food production, and power generation.

High-Performance PTFE Gaskets for Industrial Sealing
When your application demands a gasket that resists chemical attack, withstands high temperatures, and maintains integrity under load, Superlon® PTFE gaskets are the trusted solution. Their construction combines the chemical inertness of PTFE with the structural reinforcement of stainless steel, reducing blowout risk and ensuring consistent seal performance over time.
Key Benefits of Superlon® Gaskets
Exceptional Sealability Without Retorquing
Superlon® gaskets seat easily and maintain a tight, leak-free seal without the need for repeated retorquing, even under fluctuating pressures and temperatures.
High Temperature and Pressure Resistance
Engineered for performance in extreme conditions, these gaskets handle elevated temperatures and high-pressure environments without degradation or loss of sealing capability.
Chemical Compatibility and Corrosion Protection
Manufactured with pure virgin PTFE, Superlon® gaskets provide excellent resistance to a wide range of acids, caustics, and solvents, while protecting flange surfaces from corrosion.
Improved Creep and Cold Flow Resistance
The reinforced 316 stainless steel core reduces deformation under sustained loads, helping maintain gasket integrity and reducing the risk of failure over time.
Minimized Thermal Expansion
Thermal expansion is significantly reduced, preserving the seal even in applications with frequent temperature cycling or thermal shocks.
Enhanced Blowout Resistance
The perforated stainless steel core adds mechanical strength, preventing gasket blowout and increasing safety in high-stress environments.
Available Thicknesses: 1/8” and 3/32”
Common Applications of Superlon® PTFE Gaskets
Flange and Valve Sealing
Ideal for flanged connections and valve assemblies where a tight, long-term seal is essential.
Pumps, Compressors, and Heat Exchangers
Superlon® gaskets maintain sealing performance in rotating and high-stress equipment, including pump housings and compressor flanges.
Chemical, Pharmaceutical, and Food Industries
PTFE’s non-reactive properties make Superlon® gaskets suitable for systems involving harsh chemicals, clean-in-place (CIP) processes, and sanitary applications.
