Piston Seal Kit
Set of 3 x Piston Seals for MK4 Hill Pump
The classic symptom of a problem with this seal is resistance on the upstroke and tendency
to recoil back downwards. The piston seal is the workhorse of the pump and it's life can be
dramatically shortened by overheating and a lack of lubrication. To maximise the life of this
seal please follow the advice on pumping and lubrication in our instructions.
