Diesel Hand Pump Rubber Seal

Diesel Hand Pump Rubber Seal

The Diesel Hand Primer Pump Rubber Seal is a key sealing component used in the fuel system of Volvo FH12, FH13, FM9, and FM12 trucks.
It is made from fuel-resistant synthetic rubber (NBR or Viton) and ensures proper vacuum and sealing during manual priming or air bleeding of the fuel system.

This rubber diaphragm or plunger seal enables smooth suction when the hand pump is pressed, allowing diesel to move from the fuel tank to the filter housing. A high-quality seal prevents fuel leakage and pressure loss.
