trying to match up a hose end i got, is this one the straight female JIC swivel with 3/4-16 threads for a -10 hose?
Answer by: Customer Support on May 11, 2025, 4:48 PM
Match it up by the connection details. End 1 is a 3/4-16 female JIC 37 degree flare swivel, and the hose side is for -10 hose. It is a straight, two-piece reusable steel fitting in the 4401 series reduced bore style.
Question by: Rick S on Nov 23, 2025, 2:28 PM
fitting says -10 hose but the thread end is 3/4-16, so is this one of them reduced bore setups where the two sizes dont match up?
Answer by: Customer Support on Nov 25, 2025, 9:32 AM
Correct, the bore through the fitting is sized down relative to the hose end, which is what "reduced bore" means on these. The hose side accepts -10 hose and the swivel end runs a 3/4-16 thread with a 37-degree JIC flare seat. Those two dimensions serve different purposes, so the mismatch is intentional, not a listing error. That configuration is pretty common when you need to step down flow or connect into a port that doesn't match the hose ID directly.

fitting says it's reusable -- does that mean I can pull it off one hose and put it on another, or is it more of a "reusable during original assembly" kind of thing?
Answer by: Customer Support on Feb 22, 2026, 6:28 AM
Reusable in this context means you can disassemble and reassemble the fitting onto hose without needing to scrap it after one use. No mandrel is required for installation, which is part of what makes the process repeatable. That said, always inspect the fitting carefully between uses for any deformation or wear before putting it back into service.
