Danfoss / Eaton Hansen and Gromelle 3946 Auto-Flo 23 Series Plug

Description & Features

Designed for general pneumatics, air tools, and construction applications, the Danfoss / Eaton Hansen and Gromelle 3946 Auto-Flo 23 Series Plug is a male half quick disconnect coupling built for reliable, tool-free connection and disconnection in demanding service environments. Its push-to-connect end type and ball lock internal mechanism allow fast coupling without requiring special tools, while operating pressures that exceed ISO 16028 standards make it well suited for high-demand pneumatic systems.

Constructed from carbon steel with a Buna-N seal, this plug is rated for use down to -40°F and delivers a flow rate of 209.22 gallons per minute. It meets US Industrial Interchange, ISO 6150 Series B, and A-A-59439 compliance standards. The line/hose/tube end accommodates flexible connections across a range of pneumatic setups, and the Hansen sub-brand designation reflects its compatibility within the broader Eaton Aeroquip coupling family.

Product Questions & Answers (2)

Question by: Debbie M on Mar 19, 2026, 11:57 AM
got a Hansen Auto-Flo 23 series coupler on my air line, is this 3946 the right plug half for it?
Answer by: Customer Support on Mar 21, 2026, 10:59 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.
