description

Flange gasket is static sealing part for flange joint of drive assembly. It fills tiny gaps between flange faces, isolates gear oil to avoid leakage and prevents sand and water from entering precision mating surfaces of gears and bearings. Broken, hardened, crushed or aged gasket will cause oil seepage at flange. Continuous oil leakage leads to oil shortage and wear, and damages gears and bearings.

FAQ 

Q：Can I keep using the gasket if it only seeps slightly?
A：Long-term use is not recommended. Leakage will get worse once the paper gasket ages, which may cause oil shortage damage.

Q：Can I reuse the intact old gasket?
A：No. The gasket has permanent compression deformation after clamping, re-installation will lead to poor sealing and oil leakage.

Q：Is sealant required for installation?
A：Follow original specification. Some flanges only rely on gasket. Apply thin even coat if sealant is needed, avoid thick sealant blocking oil passage.

Q：What causes oil leakage shortly after gasket installation?
A：Uneven or distorted flange surface, uneven bolt torque, reversed gasket and burrs or dirt on flange face are common causes.
