4. FAQ

Q: What is this gasket and what does it do?

A: This is a thin, flat static gasket, typically used to create a leak-proof seal between two flat mating surfaces, such as pump flanges, valve bodies, or cylinder end caps. It also compensates for minor surface imperfections.

Q: What’s the correct installation process?

A: First, thoroughly clean both sealing surfaces to remove all oil, dirt, or old gasket residue. Align the new gasket precisely with fluid ports and bolt holes, then tighten the bolts evenly in a crisscross pattern to ensure uniform pressure distribution.

Q: What are common causes of gasket failure?

A: The most frequent issues are dirty or scratched mating surfaces, uneven bolt torque leading to warping, using the wrong gasket thickness, and reusing a previously compressed gasket.

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

A: With clean surfaces and correct torque, it can last for years of continuous service. It only needs replacement when the joint is disassembled for maintenance or repair.
