• High-performance composite fiber material, outstanding oil resistance, heat resistance and medium corrosion resistance, maintain stable sealing performance under alternating hot and cold cycles of engine working condition.
• Excellent compression and rebound performance, can compensate tiny deformation of metal flange surface caused by long-time vibration and thermal expansion, avoid seal gap opening under dynamic load.
• Precision one-piece stamping forming, accurate hole location and smooth cutting edge, easy quick alignment during assembly, no on-site cutting, trimming or hole drilling required.
• Reliable sealing effect, effectively block leakage of engine oil, cooling water and compressed air, prevent sediment, muddy water and fine dust entering internal assembly to scratch precision components.
• Strictly follow OEM dimension specification, fully compatible with original mating surface, direct replacement for old gasket, greatly reduce maintenance time and machine downtime cost.

FAQ 

Q1：What signs indicate the gasket needs replacement?
A1：Oil or water seepage at joint surface, gasket hardening, cracking, breakage, permanent compression set. Leakage will cause oil consumption increase or overheating.

Q2：What should be noted during gasket installation?
A2：Clean the mating surface thoroughly, remove old gasket residue and rust. Install new gasket flat, do not skew or fold. Tighten bolts in cross sequence to uniform pressure.

Q3：What are the common causes of gasket damage?
A3：Aging and heat fatigue; uneven bolt tightening; metal surface scratch and deformation; excessive pressure or temperature surge.

Q4：Can old gasket be reused after disassembly?
A4：Not recommended. After disassembly, the gasket has produced compression deformation, rebound performance drops greatly. Reuse will easily lead to leakage, must use brand-new gasket for reassembly.

Q5：How to inspect gasket in daily maintenance?
A5：Check joint surface regularly for traces of oil or water seepage. Observe whether there is oil dirt accumulation around the seam.

Q6：What trouble will failed gasket bring?
A6：Medium leakage will occur. Oil leakage leads to insufficient lubrication; coolant leakage causes engine overheating, which may cause severe damage of engine components.
