🔷 What is a PTFE Gasket?

A PTFE Gasket is a non-metallic gasket made from polytetrafluoroethylene, a thermoplastic material with excellent chemical resistance and low friction.

PTFE gaskets are used to:

✔ Seal flanges, valves, pumps, and equipment
✔ Resist corrosive chemicals and acids
✔ Prevent leakage in pipelines
✔ Operate at moderate temperature and pressure

PTFE gaskets are ideal where metallic gaskets may corrode or fail due to aggressive chemicals.

🔷 Types of PTFE Gaskets

1️⃣ Full-Faced PTFE Gasket

• Covers entire flange face

• Provides uniform sealing

• Suitable for standard raised face flanges

2️⃣ Ring Type PTFE Gasket

• Fits inside flange bore

• Saves material

• Ideal for high-purity or aggressive chemical systems

3️⃣ PTFE Encapsulated Gasket

• Soft core (graphite or rubber) encased in PTFE

• Combines chemical resistance with flexibility

• Excellent for moderate pressure and temperature applications

4️⃣ Expanded PTFE Gasket

• Soft, flexible, and self-lubricating

• Perfect for irregular flange surfaces

• Reduces risk of stress cracking
