2271200 227-1200 Sleeve Inj X6 W/ Orings 3107257 Fits CAT C7

Six New Aftermarket Replacement Fuel Injector Sleeves with O-Rings for Caterpillar (Cat) C7 and C9 Engines

This kit includes six fuel injector sleeves (cups) complete with O-ring seals for Caterpillar C7 and C9 HEUI-style diesel engines. The injector sleeve seals the injector bore in the cylinder head, preventing coolant and combustion gas leaks around the injector body. Replacing sleeves and O-rings together during injector service restores a leak-free seal and is standard practice during C7 and C9 injector overhaul.
