  • OT Regulator Repair

    Hi Guys,
    Long time reader.I have learn a lot from this forum in the last few years ,really like the across all time zones flavour it takes on .
    My question is there a way to repair/rebuild/fix the o2 regulator on my smoke wrench?
    Its a Proline 250T-80.
    Problem: Output pressure goes off high side of scale even with ajuster screwed all the way out.
    Thanks ************GG*************
    P.S. As I am new to computers and only type with two fat fingers all errors are of my own makeing. I find it funny that I can make chips and hold to .001 but cant master this dell desktop.

    Sounds like a bad valve seat. There are places that repair them but I have never even heard of that brand. Airgas does a trade in on new regulators.

      I've taken long unused regulators around to a welding repair shop just to get checked and verified before something unexpected happened. They checked, replaced gauge covers, gave me a clean bill and charged only a pittance. I thought it was worth having an experienced, professional eye on them.

        Take it to a certified regulator guy.

        My Purox acetylene regulator was creeping up on pressure to a dangerous point, so i took it in , he rebuilt it, cost was $22.00 .

        (Not worth messing with these things.)

          Take it to a pro.
          There have been fatalities from the damn things.

            When I bought my used oxy-acetylene rig, the oxygen regulator had a busted diaphram. Took both gauges/regulators to local welding supplier and had them both repaired and tested. Total bill was $63. That seemed reasonable to me, especially the peace of mind knowing they were tested by pros.
            Cheers,

              Regulator

              I recall an older regulator that was used on crude oil service that had a seat block with four faces. When it started acting-up it was easy to open the unit and rotate the seat to a new surface. The seat material appeared to be Nylon.
