Title: 11377 Valve problem
Post by: ZigZagMan1949 on December 22, 2014, 03:30:46 PM
      My 1377 seemed to be losing pressure if it sat more then a minute fps dropped off 30+ fps 0r more if it set longer. So I took the pistol apart and found that when the hole for the set screw was drilled they pierced the air chamber. Has anyone else found this to be a problem? I was going to replace it with a high performance brass one anyway but now am wondering if this something that I should watch for in a replacement valve also?
      Any input or information would be helpful.

I picked up some high strength pipe dope (Teflon) at Menards. It's supposed to hold up to high pressure. Haven't tried it yet, but it might help you out some.

  What is the one, so at least I know to check that right off the bat. Gun is still under warranty so there sending me a new pistol. Will check around for the Teflon also as I want to push this as far as possible as far as pressure is concerned. What could come in hand for sure.
  Thanks to you all for the reply can always get an answer on here even if it's not the one you want sometimes.

  Good shooting to all and to all a good night,

You might get lucky but PTFE tape is meant to seal tapered fittings.  Can't hurt to try it but from my experience, carefully loading the threads (both male and female) with an epoxy has a better chance of sealing.  I'm not familiar with what is in the vicinity in this case so just be mindful of where any squeezeout will go and either try to prevent it or orient the parts for curing so it will pool in an innocuous or advantageous place.
