Designed for container use in pressure gauge installations to minimize excess gas discharge in the event the pressure gauge is sheared. A suitable shut-off valve should be installed between this valve and the pressure gauge to allow convenient gauge replacement.
Unit of Measure



  • Precision machined.
  • Suitable for use with all 1/4" M.NPT pressure gauges.
