Answer by: Customer Support on May 15, 2025, 4:59 PM
This Eaton Aeroquip fitting is constructed from carbon steel, so it's durable enough to handle the demands of refrigeration applications using SAE 37° flared connections.
Question by: Brenda T on Jun 10, 2025, 3:04 PM
trying to swap out a -12 hose end, is this FJ3901-1212S the right one for a 1 1/16-12 hose ID with a 37 degree flare?
Answer by: Customer Support on Jun 12, 2025, 7:52 AM
It matches a -12 hose dash size and calls out compatibility with a 1 1/16-12 inch hose ID, and the connection style is SAE 37 degree flare with a female end.
Question by: Wes H on Mar 18, 2026, 7:18 PM
What kind of hose does this fitting hook up to, and is it a female connection on both ends or just the one?
Answer by: Customer Support on Mar 20, 2026, 6:45 AM
Female end on the hose side, sized for a -12 hose dash with a 1 1/16 - 12 inch hose ID. The other end runs SAE 37 degree flare. So you've got a female flare connection meeting up with your hose end, which is a pretty standard setup for refrigeration line work using that style of flared fitting.
