Our hose end swivel fittings are top-of-the-line. They are nickel plated for corrosion resistance. The amazing thing is that they are rated to 1200 PSI and -60*F. They are easy to install on any hose with 1/4" ID and 3/8" OD. The rigid plastic strain relief looks good and keeps the hose from kinking when pulled sideways. Note, you will need a 3/4" compression fitting wrench to tighten or you may strip the plastic hex on the strain relief. This will not be warranted.
The only thing that should be specified about this product is that it only contains the swivel fitting for one end of the hose. That's fine for me since that's all I needed, but someone needing to entirely rebuild a PowerTank hose will need to order two.
Also, it includes both the inner swivel fitting and the black spiral outer fitting as well.
