I have a vacuum pump for bleeding brakes solo. The hose/adapters seem to fit tightly on the bleeder fitting but I seem to be sucking air from around the threads. I’m only opening the valve about 1/8-1/4 turn but it still seems to be leaking. I’ve used silicone grease but that seems to wear off quickly. I’m not too sure on Teflon tape. Any tips on sealing the threads?
