4. FAQ

Q: Why adopt fiber composite material with metal lining for this gasket?
A: Large transport vehicles run continuously with severe vibration and temperature changes. Non-asbestos fiber has excellent compression recovery to avoid oil leakage after long bolt compression. The built-in thin metal strip enhances structural rigidity and prevents gasket tearing during assembly. NBR auxiliary rings cope with normal temperature oil sealing at small hole positions, balancing cost and service life.

Q: What color and surface features do these gaskets have?
A: The main flat gasket is light cyan green, with uniform thickness and pre-punched precise mounting holes, and thin metal anti-tear strips embedded on the sealing edge. All matching NBR sealing rings are solid black with smooth round surfaces. Different sizes are easy to distinguish during on-site installation without mixing up parts.

Q: What temperature range can this gasket kit adapt to?
A: The main fiber gasket works steadily from -32°C to +125°C, and NBR rubber rings support -30°C to +100°C. It can adapt to low-temperature outdoor work in winter and long-hour high-temperature operation in summer without softening or hardening failure.

Q: What troubles will low-quality gaskets bring to transport equipment?
A: Cheap gaskets use loose recycled fiber without metal lining. They will deform and swell after contacting engine oil, leading to continuous oil seepage at the housing joint. Serious leakage will cause insufficient engine lubrication, accelerate internal component wear, and bring extra oil consumption and long equipment downtime losses.

Q: What key installation points should operators follow?
A: First, fully clean the housing flange to wipe off old gasket residues and carbon deposits. Second, place the gasket flat without folding or offsetting, the metal lining side close to the high-temperature oil side. Third, tighten fixing bolts crosswise in batches to avoid partial extrusion damage. Do not coat thick sealant to prevent blockage of oil passages.
