Question by: Gene P on Dec 24, 2025, 7:01 PM
does this hook up to standard ag equipment fittings or do i need an adapter? trying to figure out if it'll mate up with what we already got on the line.
Answer by: Customer Support on Dec 26, 2025, 6:03 PM
Built to ISO standard 7241/1 Series A dimensions, so it mates with other Industrial Interchange couplings that follow the same spec. The socket end is a 1/4-18 NPTF female pipe thread, which is common on a lot of agricultural and construction equipment. If your existing fittings follow that ISO series and use a matching male half, you should be good to go without an adapter.
Question by: Scott S on Mar 12, 2026, 9:01 AM
Will this fitting work for hydraulic fluid transfer on my tractor?
Answer by: Customer Support on Mar 13, 2026, 12:13 PM
It's designed for hydraulic fluid transfer, and it's often used on agricultural equipment like tractors, as well as construction equipment.
Question by: Troy M on Oct 3, 2025, 6:36 PM
got a -04 line already, is this the right female half with 1/4-18 female pipe threads?
Answer by: Customer Support on Oct 5, 2025, 6:43 AM
You’re looking at a -04 size 5600 Series Industrial Interchange female half with a 1/4-18 female pipe thread (NPTF). Both ends on this one are female, and it’s the socket style with a push to connect interface on the coupling side.
Question by: Carl C on Jun 25, 2025, 9:47 PM
does this thing work on agricultural equipment or is it more of a shop/plant type fitting
Answer by: Customer Support on Jun 27, 2025, 8:13 PM
Both, actually. The 5600 Series sees regular use in agricultural equipment, in-plant manufacturing setups, and construction machinery. It also fits dump trucks, snow plows, and maintenance vehicles. The PUSH-PULL ball latch makes hookup and disconnect fast when you're out in the field and don't want to mess around.
