Perkins original  20R-1268 Diesel Injector High Pressure Fuel Nozzle for 3512B 3512C 3516B 3516C Engineering Machinery System Accessories  original new injector

The Perkins 20R-1268 fuel injector is an OEM-manufactured replacement component designed specifically for the Perkins 3500 Series diesel engine platform, including the 3512B, 3512, 3508, 3508B, 3516, and 3516B configurations. This electronic unit injector operates within a turbocharged, water-cooled, electronic injection fuel system built for continuous duty industrial operations. Authorized part number 20R-1268, along with CA20R1268, 3512B, and 3508B, serves as a direct factory reference for verifying genuine Perkins specifications across procurement, distribution, and field service channels.

Extensive cross-reference compatibility is provided through part numbers 392-0204, CA3920204, 172-4675, 386-1756, 250-1304, 229-0200, 133-3345, 10R-1278, and 10R-1255, allowing fleet operators and maintenance teams to consolidate inventory under a single approved replacement. The injector is suitable for generator sets, prime power plants, marine vessels, tugboats, offshore platforms, mining equipment, pump drives, compressor systems, and emergency backup power systems deployed across power generation, marine, oil and gas, mining, industrial manufacturing, and data center facilities.

Precision manufacturing to Perkins engineering tolerances ensures consistent spray atomization, high-pressure injection performance, and long service life under demanding load conditions. Wear-resistant alloy steel construction and corrosion-protected surfaces make this injector suitable for marine and offshore environments where humidity, salt exposure, and temperature extremes are common. Installation follows standard OEM procedures including fuel system isolation, bore cleaning, seal replacement, torque application, fuel priming, and post-installation leak inspection to maintain system integrity and engine performance.
