What do I need and where do I get fittings to refill my small bottles? I have a large mother bottle. Went to Praxair and they don't have anything. The guy acted like what I was trying to do was crazy.
once every 5 years for 20 bucks is bullshit? Hell most shops swap tanks so the chances of you needing to pay for a hydro test is slim unless it takes you 5 years to go threw a mother bottle.Around here its bullshit they want the bottle certified and bunch of b.s.. Im going to start using nitrous.
Try a welding supply shop.
