Question by: Dustin C on Nov 15, 2025, 10:33 AM
trying to match up a hose end i’ve got, is this the straight female JIC swivel for a -04 hose with 7/16-20 threads?
Answer by: Customer Support on Nov 16, 2025, 10:34 AM
The key identifiers line up as a straight steel flat crimp fitting for -04 hose, with a 7/16-20 female JIC 37 degree flare swivel on the threaded end.
Question by: Hubert K on Nov 2, 2025, 9:51 PM
What size hose does this fitting work with? Just wanna make sure it'll fit my setup.
Answer by: Customer Support on Nov 4, 2025, 6:03 AM
It's made to work with a -04 size hose.
Question by: Curt J on Jul 26, 2025, 7:49 PM
no mandrel needed on this one, right? trying to figure out if we can just crimp it straight with what we got on hand
Answer by: Customer Support on Jul 28, 2025, 6:56 AM
Correct, no mandrel is required for this fitting. That simplifies things considerably on the shop floor since you're not hunting down extra tooling before you get started. It's a straight configuration with a 7/16-20 female JIC 37 degree flare swivel end, built to work with -04 hose size, so as long as your crimp setup handles that hose and fitting combination, you're good to go.
