5. FAQ

Q: Can you tell the advantage

A: This thin ring gasket is installed between two flat, stationary mating faces—like pump flanges, valve bodies, or cylinder end caps—to create a leak-tight barrier and compensate for minor surface imperfections.

Q: Can you tell the advantage of PTFE material ?

A: Yes, as we know , the PTFE material has:

• Near-Zero Friction: Teflon is incredibly slippery. It allows steel transmission shafts and clutches to rotate at thousands of RPMs directly against the seal without creating destructive heat or friction.
• Extreme Heat Resistance: It can easily handle transmission fluid temperatures well over 200°C (392°F) without softening or breaking down.
• Chemical Immunity: Transmission fluid contains harsh detergents and additives, but PTFE is chemically inert—meaning the oil cannot corrode or weaken it.

Q: What common issues lead to gasket failure?

A: Common causes include poor surface preparation, uneven bolt torque, using the wrong material or thickness for the application, and reusing a previously compressed gasket.

Q: How long can a properly installed PTFE gasket last?

A: Under ideal conditions with clean fluid and correct torque, a PTFE gasket can last for years of continuous service, only requiring replacement if the joint is disassembled.

Q: Can I reuse an old gasket?

A: No, it is never recommended to reuse a gasket. Once compressed, the material develops a permanent compression set and cannot conform to the mating surfaces again, leading to leaks. Always install a new gasket during reassembly.
