Trying to match up a fitting i pulled off a -06 hose, is this one the straight swivel with 5/8-18 female SAE flare threads?
Answer by: Customer Support on Sep 29, 2025, 4:14 PM
The key callouts are the thread and hose size. This part is a straight, reusable socketless brass fitting for -06 hose, with a 5/8-18 female SAE 45 degree flare swivel on the threaded end.

fitting says socketless reusable - does that mean i can pull it off the hose and put it back on a different one if I need to?
Answer by: Customer Support on Oct 17, 2025, 6:57 AM
Socketless reusable fittings are built so you can remove and reinstall them without needing a crimping machine or special tooling. That's the whole point of the design. You can pull it off one hose and put it onto another as long as the hose matches the -06 size rating. It's a practical option for field repairs or situations where you're reusing hose assemblies rather than building new ones every time.

got a -06 hose here. is this the kind of fitting that’ll screw right on and still let me clock it where i need it?
Answer by: Customer Support on Jan 18, 2026, 7:13 AM
With the female SAE 45 degree flare swivel end, you can tighten it down to the mating flare and still rotate the swivel to get your hose pointed the direction you want. It is a straight fitting made for -06 hose size.
