2 Bolt & 3 Bolt Custom Exhaust Flange Gasket
Steel flange gasket Title:
Exhaust flange gasket 2 bolt & 3 bolt gasket flanges from China
Flange Gasket Auto Parts Introduction:
The "2-Bolt" or "3-Bolt" in the name refers to the number of bolt holes on the flange (symmetrically distributed with 2 or 3 holes), which is suitable for the structural requirements of different exhaust systems.
Core functions:
High temperature sealing: resistant to exhaust gas erosion, preventing exhaust gas leakage and noise generation.
Vibration buffering: Absorbs high-frequency engine vibrations and reduces the risk of fatigue fracture of metal connectors.
Detachable maintenance: easy to replace exhaust components such as mufflers and catalysts.
Material classification:
Graphite metal composite pad: good elasticity;
Pure graphite pad: easy to compress, not resistant to mechanical impact;

Special application scenarios:
Variable valve exhaust: Flexible graphite and stainless steel skeleton gaskets should be selected to adapt to the impact of valve opening and closing.
Hydrogen powered vehicle exhaust: Due to the strong corrosiveness of water vapor, SUS 316L stainless steel gaskets must be used.
| Model Number | 2 Bolt Flange Gasket | 3 Bolt Flange Gasket |
| Bolt Distribution | 180 ° symmetrical (straight line type) | 120 ° triangle uniform distribution |
| Anti deformation ability | Long span is prone to warping | Uniform stress dispersion |
Adaptability check
Measure the center distance of the flange and the bolt hole diameter.
Confirm the thickness of the gasket. If it is too thin, it is prone to crushing, and if it is too thick, it will affect the sealing.
Installation specifications
Clean the surface: Use a wire brush to remove carbon from the flange area, and wipe with ethanol without residue.
Torque control:
2-Bolt: Tighten diagonally twice;
3-Bolt: Increase in three steps in triangular order;
Prohibited sealant: High temperature carbonization can actually cause leakage;
