4. FAQ
Q: Why use stainless steel, fiber and NBR three kinds of materials together in one kit?
A: Mining trucks generate high exhaust temperature and continuous engine vibration during operation. Multi-layer steel gaskets resist high temperature and shock without cracking. Fiber composite gaskets have good compression recovery to prevent coolant and oil leakage. NBR O-rings keep stable elasticity under low temperature for auxiliary sealing points.
Q: Can you briefly describe the color and appearance of each component?
A: The multi-layer metal gaskets are silver with neat laser-cut holes. Fiber gaskets are light gray with thin black rubber wrapped edges. All NBR O-rings are uniform black with smooth round surfaces. Each part has clear size differences so installers can quickly pick the right piece.
Q: What temperature range can this whole set of gaskets adapt to?
A: The stainless steel main gaskets can work steadily from -40°C up to 420°C. Fiber gaskets and rubber O-rings apply to -35°C to 130°C, which can adapt to cold winter mines and high-temperature continuous transportation scenarios.
Q: What problems will inferior gaskets bring to mining trucks?
A: Cheap gaskets are made of thin iron or low-density fiber. They will burn through or swell quickly under high temperature, leading to gas leakage, oil-water mixing inside the engine. Damaged engine parts will cost a lot to repair and cause long equipment downtime in mines.
Q: What key points should we pay attention to during installation?
A: First, clean all flange surfaces to remove carbon deposits and old gasket residues. Second, install metal gaskets with the corrugated side facing the high-temperature side. Third, tighten bolts diagonally in batches to avoid uneven extrusion. Do not coat excessive sealant on metal gaskets.
