Engineered specifically for heavy-duty automotive, marine, and industrial exhaust systems. Ningbo Kaxite Sealing Materials manufactures high-performance exhaust spiral wound gaskets designed to withstand extreme thermal shock, severe vibration, and high-pressure exhaust gas fluctuations. Explore our full range under the Gaskets category.
An Exhaust Spiral Wound Gasket is a precision semi-metallic gasket built for internal combustion engines, turbochargers, manifolds, and industrial exhaust ducts. It features alternating V-shaped metal plies (such as stainless steel or Inconel) and a high-temperature resistant filler (such as flexible expanded graphite or mica). This unique V-spring construction allows the gasket to dynamically recover under severe thermal expansion and constant mechanical vibration without blowout or leakage.
Multi-Lug Exhaust Flange Gasket
3-Bolt Flange Exhaust Gasket
2-Bolt Oval Exhaust Gasket
Exhaust systems present unique sealing challenges due to extreme thermal cycling and continuous mechanical vibration. Our engineering features ensure long-term stability:
V-shaped metal profile acts like an elastic spring, absorbing rapid expansion and contraction caused by sudden engine temperature swings.
Designed to maintain constant bolt load stress even under heavy-duty engine vibrations, eliminating exhaust gas leakage and soot blowout.
100% certified alloy raw materials with positive material identification (PMI).
Strict outer/inner ring dimensional verification for seamless flange fit.
Exhaust flanges experience extreme thermal expansion and constant vibration. Solid metal gaskets lack elasticity, while standard sheet gaskets can blow out under high pressure. Spiral wound gaskets combine metal strength with spring-like recovery, dynamically adjusting to flange movement to prevent leaks.
For marine and high-sulfur heavy-duty diesel exhausts, Type 316L stainless steel or Inconel 600 windings are recommended due to their superior resistance to high-temperature oxidation, acid condensate corrosion, and sulfur attack.
Yes. In addition to standard ASME/DIN sizes, we specialize in producing custom non-rounded, oval, and multi-hole exhaust and turbocharger gaskets based on your exact CAD drawings or sample specifications. Feel free to contact our engineering team.
