Injection Pump Seals & Gasket Kits
Injection pump seal and gasket arrangements vary by family and revision. A leaking housing or shaft does not identify every internal component requiring replacement.

DCT PARTS / LINE CARD GUIDE
Diesel Seals, Gaskets & Repair Kits
Injection pump, injector, high-pressure oil, EGR and oil cooler seal sets require precise component identification.
Find the component family before choosing a part
Injection pump, injector, high-pressure oil, EGR and oil cooler seal sets require precise component identification. An exact part number and the engine or equipment application determine what can be reviewed. A brand or product family appearing in the line card does not confirm every individual variant is in stock or suitable for repair.
Diesel Injector Seal & O-Ring Kits
Injector installation seals can isolate fuel, oil or combustion gases depending on the engine design. Mixing kit components can cause leakage or fitment problems.
Diesel Fuel-Injection Repair Kits
Repair kits may cover a limited portion of a pump, injector or supply assembly rather than a complete overhaul. Manufacturer revisions can change included pieces.
High-Pressure Oil Seals & Rail Kits
High-pressure oil systems supporting HEUI injection can use specialized rail, standpipe, port-plug and fitting seals. Oil-side leaks have distinct diagnostic implications.
EGR Cooler & Intake Gasket Kits
EGR cooler and valve gasket sets differ by engine and assembly revision. Cooler faults can involve coolant or exhaust pathways rather than fuel injection directly.
Engine Oil Cooler Gasket & Seal Kits
Oil cooler gasket and O-ring designs are determined by the engine and cooler assembly. The wrong seal may not be visible until the system is pressurized.
How to request an accurate component quote
Send your original part number, any supersession or cross-reference information, the engine and equipment details, and whether you prefer new, rebuilt, refurbished or exchange where actually offered. DCT will confirm applicable fitment, stock, shipping, return/core and warranty conditions for an actual item.
Use the component identification inquiry for unlisted items, or explore the DCT online store for products deliberately made available for direct purchase. Service components must not be shipped until DCT confirms acceptance and receiving instructions.
