Exhaust Spiral Wound Gaskets – precision-engineered sealing solutions specifically designed for high-temperature exhaust systems in aircraft, automotive, and industrial engines. Featuring spiral wound construction with flexible graphite or PTFE filler and an outer metal winding, these gaskets provide exceptional resilience against thermal cycling, vibration, and extreme exhaust gas temperatures. As a leading China exhaust spiral wound gasket manufacturer, Kaxite offers custom configurations including 2‑hole, 3‑hole, and 4‑hole patterns to match Continental, Lycoming, and other engine platforms. Available in stainless steel, Inconel, and other high-temperature alloys, our gaskets deliver reliable sealing performance in the most demanding exhaust applications.
Exhaust Spiral Wound Gaskets are specialized sealing components manufactured using a continuous V‑shaped metal strip spirally wound with a flexible filler material. This unique construction creates a resilient, spring‑like seal that maintains constant contact pressure against flange faces – even under extreme thermal expansion and contraction cycles common in exhaust systems.
Unlike standard spiral wound gaskets, exhaust versions are typically produced in non‑rounded shapes with custom bolt hole patterns to match specific engine exhaust flanges. Kaxite supplies exhaust gaskets for Continental, Lycoming, and other aircraft engines, as well as industrial gas engines and automotive performance applications. Our exhaust spiral wound gaskets are engineered with high‑temperature alloys and graphite fillers to withstand continuous exhaust gas temperatures up to 850°C while maintaining sealing integrity under vibration and pressure fluctuations.
Custom exhaust SWG with bolt holes
Designed for Continental engines and certain industrial exhaust applications. Features two precisely positioned bolt holes for secure flange mounting.
Commonly used for Lycoming engines and other aviation powerplants. Three‑hole design provides balanced clamping force across the exhaust flange.
Standard for larger Continental engines and heavy‑duty industrial applications. Four‑hole design ensures maximum sealing stability under high vibration.
Kaxite can manufacture exhaust gaskets with any bolt hole configuration, shape, or size to match your specific engine or equipment requirements.

304 SS, 316 SS, Inconel, and other high-temperature alloys – choose the right material for your environment.
Precision winding and quality control ensure reliable sealing – eliminates exhaust leaks and performance loss.
| Component | Material Options | Temperature Range | Application |
|---|---|---|---|
| Winding Metal | 304 SS / 316 SS / Inconel 600 | Up to 850°C (with graphite filler) | General / Corrosive / High-Temp |
| Filler Material | Flexible Graphite / PTFE | -200°C to +850°C (Graphite) | High-temp / Chemical resistance |
| Inner Ring (Optional) | 304 SS / Carbon Steel | Same as winding | Anti‑corrosion, anti‑blowout |
| Outer Ring (Optional) | 304 SS / Carbon Steel | Same as winding | Centering and compression control |
Custom material combinations available upon request. For exhaust applications, graphite filler with stainless steel winding is the standard recommendation.
Case Example: Aircraft Engine Exhaust Seal Replacement
An aviation maintenance provider in Florida was experiencing frequent exhaust leaks on Lycoming engines used in training aircraft. Standard flat gaskets were failing due to thermal cycling and vibration, requiring replacement every 200 hours. Kaxite supplied 3‑hole exhaust spiral wound gaskets with stainless steel winding and graphite filler for the 4‑cylinder engine exhaust flanges. The spring‑like sealing action maintained leak‑free performance despite repeated thermal cycles. After 600 hours of operation, zero exhaust leaks were reported, reducing maintenance frequency and improving aircraft dispatch reliability.
