Product Questions & Answers

got a tank that takes 1/4 NPT, would this breather vent screw right in?

Question by: Dean S on Oct 5, 2025, 5:52 PM

With a 1/4 NPT thread, it’s meant to fit ports tapped for 1/4 NPT, so it’s a straightforward screw-in style breather vent for that thread size.

Got a hydraulic reservoir that needs a breather on it, will a 1/4 NPT fitting work for threading this thing in?

Question by: Todd W on Jan 17, 2026, 4:04 PM

Yeah, 1/4 NPT is exactly what this vent uses, so if your reservoir port matches that thread size you're good to go. It's a standard thread size that shows up pretty regularly on smaller hydraulic tanks and gearboxes, so there's a decent chance it'll drop right in without any adapters.
