As soon as I need to remove my MA957 to refill the bottle I will be removing the teflon tape.
just trying to keep the discussion relevant - I can understand all the myriad ways that piping connections are made -- in the case of regulator to cylinder, tape isn't advised when I talk to welders. These folks say need for tape means the reg isn't sealing proper, I cant really argue with that. I taped my MA957s for quite a while and took flack at the shops for it, but mostly shrugged it off, because the forum guys and my Milwaukee instructions said thats how to do it. So if anything hopefully this is a discussion about how to get a great seal without lots of hassle?
When I came across permaseals it was excellent. Quicker changeover, less worry about leaks and no more taping. I have had to change o-rings on permaseals. They get ragged after a while. Lucky for me, I got the shop I exchange tanks with interested in permaseals and they now stock the orings and the two brass pieces that make up the seal.
seems the board is lighting up recently with pressurized CO2 discussion. Nice.
