These airless hose couplers work exactly as a coupler should. I needed one for a new whip and will use one other for coupling a second hose when needed. The third is a spare. Much better price than anything I can purchase locally and a great value.

Did not fit my 1/4" adapters. Would not thread into any of my existing 1/4" air hose adapters.
