Product Details

Cast 170304-PTX2878 (PTX-series rail-tube docking collar, aftermarket CRIN-bracket ferrule) behaves as a cyanided steel splice that grips the high-pressure delivery hose to the CR injector mouth on mid-tier CR platforms (non-OEM rebuild shops list it under ISDe/ISLe CR, 6DL2 CR, DCi11 CR cross-use). It shows a 24° raked face at one end and a blended metric/UNF outer thread at the other, shut with a copper flattening lamella; passed for repeated 1600–2000 bar shock pulses without creep. Not a fogging tip, not a winding-driven pod, not a rocker-pushed javelin - only a burden-carrying fuel-shift member.

Our Advantages

Restructured fuel delivery modules realize meticulous volumetric oversight, efficiently reducing interfacial frictional attrition across the full crankshaft rotational operating range and preserving residual energy reserves during waterside static standby and transcontinental bulk freight distribution. Every production batch undergoes exhaustive fatigue performance inspection at officially authenticated research sites to verify steady fuel flow throughput, upgraded joint structural robustness and homogeneous ejection performance patterns, maintaining enduring operational reliability amid continuous high-output manufacturing sequences. This flexible mechanical setup delivers complete universal component interchangeability in strict observance of OEM maintenance criteria, supporting rapid, seamless unit substitution with no mandatory angular recalibration required over recurring planned service cycles.

FAQ

1.Fogging tip, winding-driven pod, or burden-carrying fuel-shift member?

Burden-carrying fuel-shift member - raked face, threaded collar, inner duct in one steel body. No ejection hole, no pintle, no electric coil, not 04321318xx Bosch P-set, not 8N7005/7W7038 slim shell, not 364-7040 force-column, not LJBB03202A voltage-run unit, not F00RJ01659/F00RJ02057/F00RJ01191/F00RJ02993, not D5010222525/5010477777, not 4903254/C3936953 Cummins shaft, not Komatsu 6754-71-5510, not Xichai 1112030-630-0000K. It moves diesel to the CR injector; it is not the injector.

2.170304-PTX2878 dropped from 6DL2 CR into DCi11 CR bore - snap fit or seal scan?

Face tilt (24°) and blended thread form meet across CRIN-bracket injector mouths (common aftermarket hose rule), copper lamella shared. But PTX2878 stem reach lands in the 120.5 mm-class window; driving a CRIN1-short pin (F00RJ01191) or Cummins 4903254 in instead forces the plug to bottom or opens a slit, skewing the copper lamella off-axis. Check stem reach + lamella gauge before mount; a 2000 bar burst leaks outward, not as misfire. No cluster warning (merely a mechanical seal lane).
