Core Advantages

1. Multi-layer stainless steel composite high-strength structure
   
   
   Constructed with multi-layer stainless steel rigid skeleton coated with high-temperature fluororubber, far superior to ordinary paper or single-layer rubber gaskets. It delivers outstanding compression rebound performance to adapt to frequent cold-heat alternation inside the diesel engine compartment. No permanent deformation, cracking or fracture under long-term bolt pre-tightening force and intake negative pressure, effectively preventing gasket displacement and seal failure during long-distance driving.
2. Dual protection against high temperature and diesel corrosion
   
   
   The surface imported fluororubber coating adopts oil & heat resistant anti-aging formula, capable of withstanding continuous high thermal radiation from turbochargers, as well as erosion of diesel fuel, exhaust waste gas and engine oil vapor. It fundamentally eliminates intake air leakage caused by aging, hardening and cracking of inferior gaskets, stably maintaining intake vacuum balance under idle, acceleration and high-speed working conditions.
3. One-step precision die-cut forming with accurate positioning limit
   
   
   All air flow channels, bolt holes and positioning tabs are integrally stamped at one time with smooth burr-free edges. Built-in dedicated positioning protrusions lock the gasket in fixed position during installation, preventing offset when tightening bolts. Even sealing pressure is distributed over the entire contact surface to avoid partial air leakage and engine fault code triggering.
4. Rigorous multi-round factory testing & obvious troubleshooting effect
   
   
   Each batch of gaskets passes high-low temperature cycle aging test, compression rebound fatigue test and diesel immersion corrosion test before delivery. It thoroughly fixes common diesel engine faults triggered by failed original gaskets: unstable idle speed, weak low-speed torque, increased fuel consumption, black smoke exhaust, turbo lag and P0171 lean mixture fault code.
