Drum Vent for Petroleum Chemicals

This pressure and vacuum relief vent is designed for horizontal drum openings with a two-inch male NPS or NPT thread. It handles petroleum-based liquids and includes a flame arrestor, a cap with safety chain and a funnel. The brass body provides durability in industrial environments.

Brass Construction and Horizontal Mounting

The brass body resists corrosion from petroleum chemicals while the brown finish identifies the unit in the field. Horizontal orientation suits drums mounted on their side, and the male thread engages standard two-inch bungs without adapters. The integrated cap and chain keep the opening protected when the vent is not in use.

Manual Relief Limits and Regulatory Notice

Relief activates manually at pressures between three and eight psi, so the vent will not open automatically under normal temperature swings. Operators must trigger pressure or vacuum release themselves, which limits use on unattended tanks. The product carries California Proposition 65 warnings for cancer and reproductive-harm chemicals.

Questions about this item

How does the 3 psi to 8 psi relief range limit pressure build-up on a horizontal drum?

The vent opens at a minimum of 3 psi and fully relieves at 8 psi, preventing over-pressure and vacuum conditions on petroleum chemical drums mounted horizontally.

What drum opening and thread type are required to mount this brass vent?

It fits a 2 inch drum bung with male NPS or NPT threads and includes a safety-chain cap and funnel for secure installation.

How do you install the vent so the flame arrestor and manual relief work correctly?

Thread the male NPS/NPT end into the horizontal 2 inch bung, tighten the brass body, then verify the flame arrestor sits upright and the manual pressure/vacuum relief lever moves freely.
