Exhaust Gaskets for Demanding High-Temperature Sealing

Exhaust gaskets are sealing components specifically designed for exhaust manifolds, turbochargers, EGR valves, catalytic converters and exhaust piping connections. They must withstand extreme temperatures, thermal cycling, vibration, and corrosive exhaust gases while maintaining a reliable seal.

Common exhaust gasket constructions include multi-layer steel (MLS) with embossed stainless steel layers, graphite composite with metal core or facing, non-asbestos fiber with high-temperature binder, and solid metal or spiral wound designs. Each offers different benefits in terms of temperature resistance, conformability, blow-out resistance and durability.

We supply exhaust gaskets for overseas distributors, industrial buyers, automotive aftermarket, maintenance companies and OEM customers, with custom shapes, dimensions, material combinations and packaging available according to specification.

High-Temperature Capability Withstands continuous exhaust temperatures up to +1000°C depending on material.
Excellent Thermal Cycling Resistance Designed to maintain seal integrity under repeated heating and cooling cycles.
Vibration & Blow-Out Resistant Robust construction resists vibration and exhaust gas pressure pulses.
Corrosion Resistant Stainless steel and graphite materials resist corrosive exhaust condensation and gases.

Selection Guide

How to Choose Exhaust Gaskets

The correct exhaust gasket construction and material should be selected based on temperature, vibration, flange type, chemical exposure and required durability.

01

Material Construction

Choose MLS for high temperature and vibration; graphite composite for conformability and high temp; non-asbestos for low-cost moderate temperature; solid metal for extreme durability.

02

Dimensions & Shape

Provide flange pattern, bolt hole positions and dimensions to ensure accurate fit. Custom shapes can be produced from drawings or samples.

03

Operating Conditions

Confirm maximum temperature, pressure, vibration level and exposure to exhaust condensate or chemicals to select the optimal material.

04

Compliance Requirements

Specify if RoHS, REACH, or other certifications are required for the final application.

Manufacturing

    FAQ

    Frequently Asked Questions About Exhaust Gaskets

    What is an exhaust gasket?
    An exhaust gasket is a sealing component placed between exhaust manifold, flanges, turbochargers or EGR components to prevent leakage of hot exhaust gases. It must withstand high temperature, vibration and thermal cycling.
    What materials are used for exhaust gaskets?
    Common materials include multi-layer steel (MLS), graphite composite, non-asbestos fiber, solid metal (copper, steel) and spiral wound metal with graphite filler. Each offers different temperature and durability characteristics.
    What is the temperature range of exhaust gaskets?
    Temperature range varies by construction: MLS gaskets typically handle up to +600°C; graphite composite up to +450°C in oxidizing atmospheres; non-asbestos up to +250°C; some ceramic-based gaskets can reach +1000°C.
    Can exhaust gaskets be made to custom shapes?
    Yes. We can manufacture exhaust gaskets to any custom shape, with specific bolt hole positions, inner and outer diameters, based on drawings or samples.
    What is the difference between MLS and graphite exhaust gaskets?
    MLS gaskets consist of multiple embossed stainless steel layers offering high spring-back and vibration resistance. Graphite composite gaskets provide better conformability to rough surfaces and chemical resistance but may have lower mechanical strength.
    Are exhaust gaskets reusable?
    Generally, exhaust gaskets should not be reused after removal because the sealing elements may have taken a set or been damaged by heat and vibration. Always replace with a new gasket for reliable sealing.
    Is exhaust gasket RoHS compliant?
    RoHS compliance can be provided for applicable materials and documentation requirements. Please confirm the required RoHS documentation and material when requesting a quotation.
    What information do you need for a quotation?
    Please provide the gasket shape, dimensions, bolt hole pattern, material preference, operating temperature, pressure, and required quantity.
