I have a Sears portable torch kit (MAPP/oxygen) that came with a DOT Exempt Oxygen (disposable) cylinder (3000 psi) that you can't find anymore. Sears doesn't have a part number for it either. I want to convert the regulator to standard oxygen fittings. My local welding shop says they can sell me a new torch set (duh) but they won't tamper with my regulator. I checked with Praxair and they said they'd get back to me.... I'll check with Airgas here in town soon. What I really need is the correct CGA nipple that will connect to a small refillable oxygen tank. The regulator is rated for 3000 psi on the high side so I want this to be safe. Has anyone ever had a regulatory worked on, say by a mail order type company? Can you recommend anyone?
