Compressor regulator leaks from the knob before and after rebuild.
Hello I have a 33 gallon 150 psi craftsman upright oil- free air compressor, last week I noticed a small leak coming from the regulator knob.
I ordered a rebuild kit, tore her down, cleaned everything, reassembled with the new components, making sure to Lube all the I rings with the supplied lubrication packet. Reattached to compressor.
Still leaks from the knob, unless I crank her down to max psi. Then it stops. Any other setting solid air leak.
