Having issues with both the brake booster fitting and HVAC fitting leaking vacuum. Tried using pipe dope for gas lines and it didn't work. Any ideas?
if you're referring to a 37degree flare fitting --- DO NOT USE TEFLON TAPE....You could try Teflon tape on the threaded portion, are you sure you are matting 37 degree fittings to each other?
Any question of the quality of your fittings?
Anything like ^^^^ works. 592 Thread lock/ pipe sealant. Any product that contains liquid ptfe Teflon will seal a threaded component including a head bolt, vacuum, fuel, diesel Fittings, etc.As far as thread sealer I have always used ARP

Right up to 15000psi 1/2" NPT fittings, and acid service to 28% HCl for the equipment at work. Good old 592 Liquid Teflon.Anything like ^^^^ works. 592 Thread lock/ pipe sealant. Any product that contains liquid ptfe Teflon will seal a threaded component including a head bolt, vacuum, fuel, diesel Fittings, etc.
