Perfect
Living in the mountains on a dirt road our fuel nozzles on the tranfer tank are always collection dirt. We used to pack the end with a paper towel and wrap duct tape. The nozzle cover is so much better!!!!! Why this isn't carried at the local farm/ranch store I have no clue. A game changer.

Description

OPW 301M-4161 is a weighted, mushroom-style 4" Male NPT Emergency Vent. When the AST builds pressure, the weighted cast iron lid is forced up off its seat to relieve the pressure. When pressure is relieved, the lid lowers and is automatically reset. The appropriate 301 Series vent is determined by the emergency venting capacity requirements of the AST and the type of connection at the tank’s emergency vent opening. This Emergency Vent is available in 4" opening with male NPT to allow for easy installation in new or existing aboveground tanks. Various lid pressure settings determine the initial venting of the valve.

Features

  • Automatically Resets – Weighted cast iron cover reseats once the pressure in the tank is relieved
  • Aluminum Body and Cast Iron Lid
  • Epoxy Powder-Coated Cover – Prevents rusting of the cover to protect expensive finishes on ASTs
  • Lid: cast iron, with powder-coated finish
  • Body: aluminum
  • Shaft: zinc-plated steel
  • O-Ring: Buna-N
  • SCFH @ 2.5 PSI (0.17 bar): 101,000

Benefits

UL Listed & CARB Certified AST Phase 1 Enhanced Vapor Recovery (EVR) System.
