Brass Drum Vent Adaptor
The Zoro Select 08181 is a pressure and vacuum relief vent built from brass with a brown finish. It threads into a 3/4 inch NPS or NPT opening using a male connection. The unit is designed for vertical drum orientation and handles petroleum-based chemicals. A flame arrestor is not included with this adaptor.
Sustained Venting Operation
Under continuous use the vent manages both pressure build-up and vacuum conditions without a specified minimum opening pressure. The brass body resists corrosion from petroleum vapours during long-term exposure. No flame arrestor means the flow path stays open for consistent relief. The vertical mounting keeps the vent clear of liquid level changes.
Thread And Chemical Limits
The 3/4 inch NPS and NPT threads restrict installation to matching drum fittings. Brass construction limits compatibility to petroleum chemicals rather than aggressive solvents or acids. Without a flame arrestor the vent cannot meet safety requirements for flammable vapour environments. California Proposition 65 warnings apply to this product.

Questions about this item
Will the brass vent adaptor run hot or make noise if left on a drum all day?
The vent is a passive brass fitting with no moving parts, so it produces no noise and generates no heat during continuous use.
What drum opening do I need for this 3/4 in NPS/NPT male-threaded adaptor to seal properly?
You need a drum bung with a 3/4 in female NPS or NPT thread that is oriented vertically.
Can I keep using my existing drum that has a 3/4 in female NPS or NPT thread?
Yes, the adaptor threads directly into a 3/4 in female NPS or NPT opening on a vertical drum.
