    New 2 Liter Issue

    I've got an AKA 2L regulator that keeps blowing the Piston off upon air up. This happens with a PE Pops ASA which when engaged give the reg full tank pressure instantly. I'm wondering if there is an issue with the regulator or if it doesn't play nice with the POPS?

    Thanks

    these are available in two spring strengths, you may have the strong spring.

      I have the high pressure spring. I'm not sure why that would blow the piston o-ring out though.

    Mine did that on one I bought recently haven’t had time to mess with it. First time putting air to it. Figured it was just a dry oring or something.

      I've got an update on this. The regulator has the high pressure spring installed by the way.
      I've found that tank output seems to be the culprit. With a 600psi output tank regulator this isn't an issue. With a 800psi it blows the piston o-ring off.
      I'm considering trying a 90D urethane piston o-ring to see if that will help.
      For now I'll run my lower output tank regulator.

            You replaced the oring and it blew out again. 😬 anything wrong with the bore of the reg body.

          Chuck E Ducky Not visibly. Although it does definitely take some effort to push the piston back in. I'm thinking the oring might be catching that lip and tearing. I've since replaced it with a new oring that is one size smaller and 90d. That replacement oring is currently holding so time will tell if it does the trick.

            I had one that kept doing this until I switched to a different O-ring material, after that it stopped

            good thing, it startles the hell out of me when it happens

              ChuckLove I think I put in a colored one, i know a lot of people loathe them, but i dont have the same issues with them like most do.. either that or it was some kind of a urethane one i had handy.. i order a lot of various o-rings from the oring store
          Working...
