On my compressor this is leaking around the black plastic adjustment knob. Is replacing the valve the only repair for this, or is there a rebuild kit that might be cheaper?
Hi James, thank you for contacting us. There is no rebuild kit listed under your model. The pressure regulator knob comes attached to the manifold, part number PS18990701. It is not listed separately. You may need to replace it to fix the issue. We hope this sorts out your problem!
