Small service kit for Hill Spartan MK2 pumps contains 3 seals including the main high pressure one. A classic symptom of high-pressure seal damage is piston stroke resistance. To extend the life of the seal, we recommend using only high-quality silicone petroleum jelly for lubrication and pumping slowly with 15-minute breaks after every 40 pumps.
Attention, the set is not intended for the Hill MK1, MK2 and MK3, MK4 pumps, but only for the Spartan MK2 model.
