Often it is cheaper to buy a pre-made hose assy than to buy 2 re-useable fittings and the hose.
Depending on the length you need and the pressure requirements, the 1/4" size hoses should be quite affordable.
We used re-useable fittings for many years at our carwash, but we found it more economical for us to buy the hoses pre-made.
The re-useables work fine if the hose leaks near an end, and there is enough length to shorten the hose and re-use the fitting.
Most of our failures occurred in the middle of the hose. ....Cleaning the re-useable ends for re-attachment became more of a hassle than it was worth.
