Flexzilla Pro Air Hose Reusable Fitting with Ball Swivel, 1/4 in. - RP900250BS

I bought several, I've only used two, but they're very easy to install and super affordable. I used to pay quite a lot for those adapters until I found these.

Ya con este producto la manguera es muy resistente

This product is great, easy to install, doesn’t leak like my other crimp fitting on my air line. Nice quality product.

Hola esta buenísimo

I bought an air hose spool that mounts on the wall of my garage. Very convenient until the fitting that came with it somehow got bent and blew off. I didn’t want to buy a whole new spool assembly, nor did I want to buy an expensive crimping tool that I’d only use once. When I discovered this life saver, it was too affordable not to try. It was harder to install than I thought it would be. Getting the tip to grab the inside of the air hose proved a challenge. After a short struggle I could never get it flush mounted, until once I started to secure the nut that holds it together. It looked pretty secure after tightening the nut, and I’ve used it with my compressor 5-6 times since the repair, and it’s still holding strong. Compared to buying a new air hose or have a new fitting professionally installed/repaired, this was too good of a price not to try. The product quality is great and this is brilliantly designed. I did a lot of searches before finding this, so let’s hope they advertise better in the future.
