Product Details
Assembly 6211-12-3600 operates as a complete mechanical injector cartridge (holder body + integrated P-type or S-type nozzle element) calibrated for Perkins 1004-4T and 1104D-44T inline mechanical-pump drivetrains. Anchored into the cylinder head via the Perkins-spec single-stud M12×1.5 boss (early 1004) or two-stud flange (late 1104/1106), the unit integrates a Bosch-derived KDAL59P2-class guide with a 60° needle seat and M14×1.5 nozzle nut. Internal element typically a DLLA148P or DLLA155P 4-hole tip, 0.26–0.28 mm, 155°, 205–220 bar CPL-dependent. Nitrided carbon-alloy body sustains invariant spray-vector fidelity across 1,500–2,300 rpm load sweeps and −20 °C to +105 °C coolant ambient. Cross-reference lineage: Perkins 6211-12-3600 / 6211123600 / Bosch 0 432 131 360-class / Delphi 7135-series overlap in some 1104D CPLs.

Our Advantages
Synthesized from thermally stable premium metallic substrates, this high-accuracy fuel metering mechanism delivers steady flow output and uniform spray performance amid erratic pressure fluctuations and recurring thermal fatigue cycles. Every finished unit undergoes rigorous professional calibration to boost combustion efficiency, rectify intermittent functional deviations during cold startup, and prevent carbon deposit buildup within cylinder bore chambers. Optimized internal flow channel structures elevate peak torque output, cut cyclic fuel consumption, and reduce hazardous exhaust emissions. Engineered for simple tool-free installation and reliable on-site maintenance, its sturdy reinforced outer casing is ideal for commercial cargo transport, civil engineering excavation equipment and stationary generator units. Continuous batch quality inspection strictly maintains unified manufacturing standards for all outbound goods, with exclusive procurement support provided by officially certified regional supply channels.
FAQ
1.Is 6211-12-3600 the nozzle tip or the whole injector?
Whole injector cartridge-holder + built-in tip + spring + adjuster. Unlike Bosch 0 432 131 xxx (which is a bare tip), this Perkins number gets you the screw-in unit that drops into the head; no separate KDAL holder or DLLA tip purchase needed. Misreading it as a bare 131-series tip (like 0432131628) is the usual parts-counter mistake.
2.Will a 6211-12-3600 from a 1004-4T fit an 1104D-44T without changes?
Thread boss differs: 1004-4T uses single M12×1.5 stud; 1104D-44T uses two-stud flange (72 mm pitch). Same spray tip inside, different clamp geometry-direct swap jams the flange on a single-stud head. Match by head casting, not by "both are Perkins 1004-family". If your 1104D plate lists 6211-12-3600, it's the two-stud sub; a 1004-sourced single-stud unit will not seat.
