The 155-8723 HEUI fuel injector is engineered for Caterpillar 3126, 3126B, 3126E, and C7 diesel engines, delivering OE-equivalent performance across construction, heavy equipment, and industrial power applications. Built from high-grade steel alloy with a corrosion-resistant surface treatment, the unit withstands high thermal and mechanical stress in demanding operating environments. Precision-machined multi-hole spray nozzles ensure fine atomization, accurate fuel metering, and stable combustion, supporting improved fuel economy and reduced exhaust emissions.
Featuring a HEUI injection design operating at 1350–1600 bar, the 155-8723 utilizes high-pressure engine oil to intensify and precisely control diesel fuel delivery. The electronic injector is compatible with common rail system diagnostics and integrates seamlessly with standard CAT 6-pin electrical connectors. With a compact form factor—135 mm length, 20 mm diameter, and 0.65 kg weight—this direct-injection component is a reliable replacement solution for original equipment in trucks, excavators, loaders, generator sets, and fleet maintenance operations.
The injector is available in new, remanufactured, rebuilt, and aftermarket replacement conditions, all manufactured under ISO 9001 and TS16949 quality standards. It cross-references with 0R-8742, 0R-8743, 20R-5392, 169-7408, 178-6342, 111-7916, 0R-9350, 173-9272, 196-1401, 218-4109, 128-6601, 4CR0197, 232-1167, 222-5972, 2C0273, 153-5938, 155-1819, 20R-0758, 232-1171, Bosch 0445110130, and Delphi 9308-621C.
