Product Questions & Answers

this coupling got a safety vent built in, does that mean it bleeds off pressure before it fully disconnects?
Question by: Shane W on Apr 30, 2025, 11:34 AM
Yes, and that's exactly what the safety vent is there for. When you go to disconnect, retracting the release sleeve and swinging the assembly to the angled position allows any trapped air to vent before the halves fully separate. It follows ISO Standard 4414 requirements, so that venting behavior is built into how the swing design works, not something you have to manage manually.

got a box of ARO 210 and Tru-Flate male plugs in the shop, will this female coupler hook up to either one?
Question by: Steve B on Feb 15, 2026, 8:52 AM
Compatibility is the main selling point here. The Auto-Flo 23/24 Series female half is built to interchange with Industrial, ARO 210, and Tru-Flate style male plugs, and it meets the dimensional requirements of ISO 6150 Series B.

Will this connect to a standard Aro 210 fitting, or do I need some kind of adapter?
Question by: Tommy H on Jun 26, 2025, 1:53 PM
Yes, this female coupling is designed to operate directly with Industrial, ARO 210, and Tru-Flate Interchange plugs/males. No adapter should be necessary for standard connections.
