Question by: Ricky E on Feb 11, 2026, 12:45 PM
Will this here fitting work okay for hooking up some air lines in my shop?
Answer by: Customer Support on Feb 13, 2026, 8:02 AM
It's good for general pneumatics, so it should work just fine for your shop's air lines. Just make sure the pressure and flow rates are compatible.
Question by: Earl G on Dec 24, 2025, 4:15 PM
got a Hansen 400 series air line setup already. is this 408 the male plug half with the sleeve lock?
Answer by: Customer Support on Dec 26, 2025, 3:27 PM
408 is the male half plug in the Hansen 400 Series, and it uses a sleeve-lock safety mechanism with a ball-lock internal connection.
Question by: Gary T on Dec 10, 2025, 12:31 PM
does this hook up to standard industrial interchange fittings or do i need something special to mate it up
Answer by: Customer Support on Dec 11, 2025, 7:02 PM
Ball lock internals and a sleeve lock mechanism handle the connection and release, but the coupling itself meets US Industrial Interchange standards along with ISO 6150 Series B, so it mates with other compliant fittings in that same interchange family without needing adapters or specialty tooling.
