Product Questions & Answers

got a Hansen Auto-Flo 23 series coupler on my air line, is this 3946 the right plug half for it?

Question by: Debbie M on Mar 19, 2026, 11:57 AM

For an Auto-Flo 23 Series quick disconnect setup, the 3946 is the plug side and it is the male half with a ball lock internal connection. It is built to the US Industrial Interchange pattern and ISO 6150 Series B, so it matches that common 23 Series style.
