The Delphi Difference

Surface lapping of each critical component

New nozzle, solenoid, NOP spring, shim, screws, check balls in each injector

100% O-ring replacement

HTK119 and HTK121 Injector Seal Kits

Delphi offers high quality seal kits for Remanufactured Series 50 and Series 60 Injectors. These seal kits are crucial for injector performance. The HTK119 kit includes three o-rings to install one injector. The HTK121 kit includes two o-rings and one sealing washer to install one injector.

Did you know?

Remanufacturing involves the complete teardown of an injector core. At Delphi, we fully disassemble all injectors thoroughly clean and inspect each component for wear and replace with new, as necessary. Injectors are then reassembed, and each is functionally tested on specialized test equipment to ensure proper performance.
