Can one use PTFE tape to ensure a gas-tight fit on the cylinder union? The brass hose-to-cylinder connection never seems competent enough to me. Yes, I take care of my brass hose coupling, but the cylinders must get plenty of abuse from previous owners? Even the slightest dinge (technical term?) on the cylinder coupling could allow gas to escape.
Certainly, there have been a few times that I've had a whiffy gas locker - even though it's vents are clear and hose etc is new. A dealership once told me that "you have to really nip the nut up tight with a spanner". Well, I've given my spanner and nut plenty of 'Isaacs' and even hung off it a-la Robin Knox Johnston! BUT a brass- to-brass connection seems doomed to fail at some stage, especially with road movement and metal-metal imperfections.
I'm aware that there's two different types of PTFE - one for general plumbing and one for gas. Sooo, apart from getting over-zealous with tape and blocking up the aperture, is there any reason why tape can't be used
