Compressor slow to load or unload
Worn bushes and seals let the valve stick part open or shut. The kit restores smooth movement without buying a new valve.
Oil blowing back into the air filter
A worn inlet valve seal lets oil mist escape into the intake when the compressor stops. New seals close it off.
Planned overhaul
Many service plans overhaul the inlet valve at set running hours, often with the separator change, to avoid a breakdown later.
Fitting tips
Vent the compressor fully, photograph the valve before stripping it, clean the bores, lubricate the new seals with compressor oil and check the valve moves freely before refitting.
