4. FAQ

Q: What color and structural features do these gaskets have?
A: The main triangular flat gasket is off-white, with three standard mounting holes and uniform 0.8mm thickness, smooth edge without burrs. The surface is covered with thin transparent oil-proof coating. All matched NBR sealing rings are solid black with round smooth surfaces, different sizes are easy to distinguish during on-site assembly.

Q: What temperature range can this whole gasket kit adapt to?
A: The fiber main gasket works stably from -33°C to +122°C, and NBR rubber rings adapt to -30°C to +108°C. It can cope with low-temperature winter pavement construction and long-time high-load operation in summer without oil leakage or cracking.

Q: What troubles will low-quality gaskets bring to milling machine oil cooling systems?
A: Cheap gaskets adopt loose recycled fiber without anti-oil coating. They will absorb engine oil and expand quickly, leading to continuous oil seepage at the cooler cover. Serious oil loss will reduce engine lubrication efficiency, speed up internal component wear, raise oil consumption cost and cause long-time equipment halt.

Q: What key installation rules should operators follow to extend gasket service life?
A: First, fully polish the cooler cover flange to wipe off old gasket residues and oil dirt. Second, place the gasket flat without tilting or folding, the coated side faces the oil cavity. Third, tighten fixing bolts crosswise in two rounds to prevent partial extrusion damage. Do not apply thick liquid sealant to avoid blocking oil circulation channels.
