Teflon Gaskets, also known as PTFE Gaskets, are widely used for their exceptional chemical resistance, non-stick properties, and ability to withstand extreme temperatures. These gaskets are ideal for high-purity, hygienic, and aggressive fluid applications in industries such as pharma, food, chemical, and biotech.
Excellent Chemical & Corrosion Resistance
Wide Temperature Range: -200°C to +260°C
Non-stick & Low Friction Surface
FDA & USP Class VI Compliant (on request)
Non-contaminating – Perfect for sanitary processes
Inert – Does not react with aggressive media
Electrically Non-Conductive
Virgin PTFE Gasket: Pure Teflon – best for hygienic & food-grade use
Filled PTFE Gasket: Glass, Carbon, or Bronze filled for enhanced strength & wear resistance
Envelope Gasket: Outer PTFE layer with elastomer core (for flexibility and sealing)
Expanded PTFE (ePTFE): Soft, compressible – ideal for low bolt-load flanges
Standard Sizes: As per ASME B16.5, DIN, and ISO standards
Custom Cut Sizes: Available as per drawing or dimension
Thickness: 0.5 mm to 5 mm
Shapes: Ring Type, Full Face, Strip Cut, Custom Profile
Sheet Sizes: 1m x 1m or 1.5m x 1.5m PTFE gasket sheets available
Flange Sealing in Corrosive Lines
Pharmaceutical & Biotech Equipment
Chemical Processing Pipelines
Food & Beverage Processing
Semiconductor & High-Purity Water Systems
Steam & CIP/SIP systems
Q: What's the main advantage of PTFE gaskets over rubber gaskets?
A: PTFE is chemically inert and non-absorbent, whereas rubber may swell or degrade in aggressive chemicals.
Q: Can PTFE gaskets handle high temperatures?
A: Yes, they work well in -200°C to +260°C, depending on the pressure and medium.
Q: Are PTFE gaskets suitable for food and pharma applications?
A: Yes, Virgin and Expanded PTFE are FDA & USP Class VI compliant options.
Q: Do you provide PTFE envelope gaskets for glass-lined equipment?
A: Yes, we offer custom envelope gaskets with Neoprene, EPDM, or Viton® cores.
