4. FAQ

Q: What advantages does fiber composite with metal insert bring to transmission cooler sealing?
A: Articulated dump trucks run on rough roads with continuous vibration and temperature changes. Non-asbestos fiber has stable compression recovery and will not deform after long bolt clamping. The built-in thin metal insert prevents the gasket from tearing during disassembly. The outer oil-proof coating avoids fluid penetration and swelling, and matched NBR seals handle small auxiliary holes to keep long-term reliable sealing effect.

Q: What color and structural features do these gaskets have?
A: The main flat gasket is light gray, with precise pre-punched mounting holes and uniform thickness. Silver thin metal strips are embedded around the sealing edge for reinforcement. All supporting NBR O-rings are solid black with smooth round surfaces, and different sizes can be easily distinguished during on-site assembly without mixing parts.

Q: What temperature range can this gasket kit adapt to?
A: The fiber main gasket works stably from -32°C to +123°C, and NBR rubber rings support -29°C to +106°C. It can adapt to low-temperature outdoor construction in winter and long-hour high-load operation in summer without softening, hardening or cracking failure.

Q: What adverse effects will low-quality gaskets bring to the transmission cooling system?
A: Cheap gaskets adopt loose recycled fiber without metal reinforcement and oil-proof coating. They will absorb transmission fluid and expand rapidly, leading to continuous fluid seepage at cooler joints. Serious fluid loss reduces transmission lubrication efficiency, speeds up wear of internal moving parts, raises daily fluid consumption cost and causes long equipment shutdown losses.

Q: What standardized installation points should operators follow to extend gasket service life?
A: First, thoroughly clean the cooler flange surface to wipe off old gasket residues and fluid dirt. Second, lay the gasket flat without tilting or folding, let the coated rubber side face the fluid flow side. Third, tighten fixing bolts crosswise in two separate rounds to avoid partial extrusion damage. Do not coat thick liquid sealant to prevent blockage of narrow fluid passages.
