Product Details
Mark‑stamped F00RJ01224 (Bosch CRIN2 high‑pressure inlet stub, member of the Cummins ISB/QSB feed‑port component lineage, interchange counterparts F00RJ00436 / F00RJ01572 / 3979419) operates as a precipitation‑hardened steel intermediate coupling which fastens cylinder‑head‑mounted high‑pressure fuel conduits toward CR‑injector intake ports conforming to Bosch 0445120121 / 0445120236 part specifications. Supported equipment fleets comprise Cummins ISB5.9 CPL2650, ISB6.7, QSB4.5, QSB5.9, QSB6.7, Dodge Ram 2500/3500 5.9L production vintages 2003‑2007, Ram 2500‑5500 6.7L spanning 2007‑2024, plus Case‑branded and Komatsu industrial equipment frames. A 24‑degree chamfered mating face is integrated at one extremity; the opposite termination carries a Cummins‑Bosch‑calibrated external fastener assembly, sealed via a copper crush gasket. This hardware has undergone qualification for continuous cyclic pressure transients within the 1600‑1800 bar spectrum, exhibiting no residual dimensional distortion after repeated load cycles.

Our Advantages
High-grade fuel-distribution systems deliver exact rate regulation, efficiently resisting frictional scoring on annular mating surfaces throughout the complete range of engine-speed fluctuations while safeguarding residual power reserves during dock-side layovers and transoceanic cargo movements. Each factory-molded component is subjected to rigorous cyclic load testing at state-accredited measurement laboratories, validating sustained supply consistency, sound fitting toughness, and reproducible atomization accuracy. Such qualification routines ensure even real-world dependability across prolonged high-volume operational windows.
FAQ
1.Atomizer nozzle, solenoid coil unit, or pressure-resistant fuel conduit?
This component is strictly classified as a pressure-resistant fuel conduit. It has no jet orifices, no internal electric coils, and no moving piston parts. It is entirely distinct from Bosch P-type injectors (04321318xx series), slim-profile sleeve parts (8N7005 / 7W7038), pressure tower assemblies (364-7040), electric control actuators (LJBB03202A), assorted Bosch ferrules, and Dongfeng DFCV connection fittings, as well as all other listed part models. Its only function is delivering diesel fuel to Bosch CRIN2 injectors for Cummins ISB and QSB engines, with no involvement in the fuel injection operation.
2. Drop‑in mounting straight from ISB5.9 toward QSB6.7 bore housing, or pre‑fit dimensional validation mandatory prior to assembly?
The 24‑degree seat chamfer plus Cummins‑Bosch thread profile stay consistent for ISB and QSB CRIN2 injector bores; both engine ranges comply with identical high‑pressure fuel‑line specifications, and their copper crush gaskets are interchangeable. Pin protrusion length represents the decisive dimensional parameter, sitting within the approximate 85‑90 mm bracket. A 120 mm Yuchai stud (377113475) or 130 mm Volvo stem (20795255) will strike the base of the recess cavity. Conversely, the 99.7 mm MAN pin (51101016036) generates an oversize clearance gap. Either mismatch warps the copper gasket and ruins leak‑tight sealing. Always cross‑check pin extension and gasket thickness before fitting. Wrong hardware configuration exposed to 1800 bar pressure spikes yields external fuel weeping. No dashboard warning signal triggers, given this junction operates on purely mechanical principles.
