    • Tank Connection: 1/2” and 3/4” Union


  • Safety Shutoff: Stainless ball check upstream of the seat shuts off medium flow in the event of glass breakage.

  • Offset Design: Body and drain connections are offset from the tank connection for easy glass cleaning.
  • NACE Compatible: Wetted parts conform to NACE MR-01-75 specifications for sour gas service.
