fitting says reusable, does that mean I can pull it off the hose and put it back on a new one, or is that just marketing talk?
Answer by: Customer Support on Oct 29, 2025, 6:28 AM
Reusable in this case means exactly what it says. The socketless design lets you remove the fitting from the hose and reinstall it on a replacement without any special tooling or a crimping machine. That's a real advantage when you're working in the field and don't have a shop press nearby. Just make sure the hose is cut clean and square at 0.83 inches as specified, and the fitting will seat properly on the new hose.

got a -04 hose and need a straight male pipe thread end, is this the one with 1/4-18?
Answer by: Customer Support on May 20, 2025, 10:48 AM
For fit and thread match, it’s a straight brass reusable socketless fitting with a 1/4-18 male NPTF pipe thread on one end and a -04 hose connection on the other.
Question by: Howard P on Oct 2, 2025, 9:23 PM
Will this fitting work with standard NPT threads, or is there something special I need to know?
Answer by: Customer Support on Oct 4, 2025, 5:44 PM
This fitting uses a 1/4-18 Male NPT thread, so it should work fine with any standard female NPT fitting of the same size. Just be sure to use an appropriate sealant.
Question by: Janice W on Sep 7, 2025, 3:09 PM
Does this fitting need any kind of thread sealant when you put it together, or do you have to go pick some up before you get started?
Answer by: Customer Support on Sep 9, 2025, 6:17 AM
No sealant needed on this one. The 1/4-18 Male NPT connection on this Aeroquip fitting is built to seal up without tape or compound, which saves you a step and keeps the assembly cleaner overall.
