Drum safety vent for 30 to 55 gal containers

The Zoro Select 08101 is a brass pressure and vacuum relief vent designed for vertical drums holding petroleum chemicals. It fits a 2 in male NPS or NPT plug and includes a flame arrestor and a cap with a safety chain. The unit operates within a 3 to 8 psi opening range. It suits facilities that need compliant venting for flammable liquid storage.

Upgrade from basic open vents

This vent replaces simple bung caps or non-relief fittings that cannot manage pressure swings or vacuum conditions. The jump is worth it when regulations require a flame arrestor and a defined pressure range for vertical drums between 30 and 55 gal. It is not for horizontal tanks, smaller pails, or drums outside the stated capacity range.

Limits of NPS and NPT threads

The male thread seals on 2 in NPS or NPT openings only; other thread forms will not engage correctly. Brass construction suits petroleum chemicals but may not resist aggressive acids or bases. The 3 to 8 psi relief band is fixed and cannot be field-adjusted for different process pressures.

Questions about this item

Does the 2 in NPS/NPT male thread fit a standard 30 to 55 gal drum opening?

Yes, the vent threads into a 2 in NPS or NPT bung on drums from 30 to 55 gal capacity.

How do I install the brass vent without damaging the threads?

Hand-tighten the male NPS/NPT threads into the drum bung, then snug with a wrench — do not overtighten or the brass threads can strip.

When should I check or replace the flame arrestor inside the vent?

Inspect the built-in flame arrestor at least once a year or after any pressure event; replace the vent if the arrestor screen is corroded or clogged.
