Question by: Judy S on Feb 26, 2026, 8:14 AM
got a RD703 here, is it the female side of the 700 series quick disconnect or did i grab the wrong half
Answer by: Customer Support on Feb 27, 2026, 6:09 PM
Female half is exactly what the RD703 is. It is a socket style quick disconnect coupling in Eaton Aeroquip’s Hansen 700 Series, meant to mate with a compatible 700 Series male half.
