Product Details
Etch-marked 2872393 (Cummins ISB6.7/ISL/QSB-series high-pressure injector feed connector, Bosch CRIN2 supply class) acts as a nitride-treated steel relay that bridges the cylinder-head pressurized fuel line to the Bosch-based CR injector side port on Cummins ISB4.5/ISB6.7, ISC8.3, ISL6.8/ISL9, QSB5.9/QSB6.7, QSL9, Dongfeng Tianlong ISDe, Komatsu SAA6D107E-1, and Ram 3500 6.7L platforms. It carries a 24° tapered seal seat at one end and a Cummins/Bosch hybrid external thread at the opposite end, fitted with an O-ring (3882589-class) plus copper crush washer; cleared for sustained 1600–1800 bar pulse loads without permanent set. Not a spray tip, not a solenoid pod, not a cam-driven lance - purely a pressure-bearing fuel-transit segment. Bosch cross: F00RC00647 / F00RJ01831; siblings 2872288 / 2872395 / 3975703.

Our Advantages
Task‑optimised fuel allotment assemblies render ultra‑precise volumetric oversight, sharply dampening paired‑contact frictional erosion throughout the full spectrum of crankshaft rotational velocity brackets and sheltering stockpiled energy reservoirs amid seaport quiescent idle states and transoceanic bulk‑cargo haulage undertakings. Every production grouping undergoes gruelling cyclic‑lifespan scrutiny within officially sanctioned metrological assessment facilities to authenticate stable fluid transfer proficiency, toughened junction structural compactness and synchronised atomised ejection homogeneity, maintaining credible prolonged on‑site functionality across non‑stop high‑yield fabrication cycles. This adaptable mechanical compound features comprehensive inter‑component replaceability pursuant to unreserved observance of OEM service mandates, permitting expedited, fault‑immune component replacements without mandatory angular realignment over periodic pre‑scheduled servicing phases.
FAQ
1.Spray tip, solenoid pod, or pressure-bearing fuel-transit segment?
Pressure-bearing fuel-transit segment. No mist holes, no coil, no needle. Not 04321318xx Bosch P-set, not 8N7005/7W7038 slim case, not 364-7040 drive-column, not LJBB03202A electric pack, not F00RJ01659/02057/01191/01919/02993, not D5010222525/5010477777, not 6126300920004/J5600-202/0740601, not Iveco 503135357, not 4903254 (close Cummins sibling, different sub-rev), not Komatsu 6754-71-5510. Routes diesel to Bosch CRIN2 on Cummins ISB6.7/ISL - not the injector.
2.2872393 from ISB6.7 into ISL9 head - snap fit or seal audit?
24° seat + Cummins/Bosch thread register across ISB/ISC/ISL CRIN2 ports (shared Cummins CRIN2 hose norm). Shaft sits in the Cummins 6.7/8.9 CRIN2 span; a Bosch F00RJ01659 (120.5 mm) or 4903254 forces bottom-out or gap, twisting O-ring + copper washer off-center. Check shaft length + ring gauge pre-fit; 1800 bar breach = exterior seep, no dash code. Pure mechanical seal lane.
