Flexzilla Pro Air Hose Reusable Fitting, 1/4 in. - RP900250

This is the same fitting that comes mounted to the "Flexzilla Pro" hose assemblies. The built in strain relief is more flexible compared to the original series. I used these on a different brand (Magnum) 1/4" hybrid hose and the fit was perfect. Those crappy hose clamp type fittings cut into the hose and are always getting snagged on whatever is in your work area.The Fexzilla fittings do cost more but I think they are worth it, a well made design.

I used this to replace the factory fitting on my 1/4" coil hose. This piece is very high quality with great fit and finish, and it's incredibly quick and easy to install. Depending on the material of the hose you are repairing, it may require a fair amount of force to get it over the barb. I was having a difficult time getting mine on so I heated it up slightly and it went on with ease. The compression fitting pinches the hose tight in place so there is no way it will come off. I set my regulator to its max pressure at 160psi and dipped it underwater to check for leaks but didn't see so much as a trace of a bubble forming after several minutes, it seals up tight!

Perfect fitting, bye bye Crimping

You won't find a better air hose connection than this. I couldn't tell you how many times I've cut or damaged an air line and just shorten it with the reusable connection. Buy far if you're a 310T or 310S these are great.

The media could not be loaded. I bought a couple of the 1/4" fittings so that I could split a 50' hose into 15' and 35'. The spiral portion is plastic and provides much better strain relief than the stiff rubber that they use on the original flexzilla hose. The two fittings (barb and cap) are made of a strong aluminum that's been anodized to be black. I was able to really wrench the fittings together and nothing deformed or stripped. However, some of the black scratched off, so i assume that after years of use there wont be much black left and they'll just be silver aluminum.Cutting the flexzilla hose was easily done with a razor blade. Do make sure you get a nice 90 degree cut then you can go ahead and slip the strain relief on followed by the threaded cap. Once those are on the hose you can go ahead and press the barb into the hose. This takes a decent bit of force but can easily be done without adding any lubrication. Just make sure you get the hose fully seated on all sides.After the hose is fully seated on the barb you can pull back the cap and thread it on. You'll need two wrenches to tighten it down. Keep going until it wont go any farther.Now you can slide the strain relief up. It is designed to click into place, however it takes wayyyy more force than you can muster with just your hands. I had to jam the tip into the floor and lean my body weight onto it before it would click on. I don't think it's ever coming off, so that may be an issue if you plan on reusing this multiple times.The tip thread is tapered to yield a nice seal when you attach your final fitting. I was left with roughly 1/8" thread still exposed after i tightened things down.You could certainly get by with just inserting a normal barbed fitting and using a hose clamp, but this thread-on cap approach yields a much nicer result. It also doesn't have any sharp parts exposed, unlike a hose clamp.
