KOOTANS4pcs Brass Hose Barb Fittings 1/4" Hose Barb to 1/8 NPT Male Thread Air Hose Fittings Brass Quick Coupler Air M Type Adapter Connector Fitting

These do exactly like they are supposed to. They screw in well.The barbs grip really well. Have fun trying to take a hose back off if you thought you was going to do a test fit. They don't want to release, you may have to cut the hose off it. In closing, they do exactly what they are supposed to do. the price was right when I bought them. I'd buy again if they were still the best price.

The threaded section is short, the end is overly large. I had to cut the threads deeper so that it was small enough to start in my equipment, which cut into the hex section. I used one on my welder for the gas supply. The threaded section should be 1/8" longer so that it is smaller and has enough taper to seat properly.

Does exactly what it says on the tin. Hose mounts on one end, screw the other end into an electric valve, and Bob’s your uncle. I used these with a 12-volt valve controlled by an Arduino and they worked great...which is to be expected, I suppose, since they’re very simple devices. I mean, it’s not like I ask them to brush my cat or make toast or anything.

I needed these to convert a 3/8 flare shielding gas hose to 1/4 NPT. They arrived next day at a great price.I'm not sure why the title incorrectly says "M Type Quick-Connect". They are hose barb and require hose clamps.

Bought for after market Raptor 700 cylinder that came without the oil drain back, works great.

Perfect fit, threads well cut, barb machined well. Does the job I bought it for.

If I had ordered the correct size it would have worked perfectly. Unfortunately I messed up on it. Otherwise a great quality part and would definitely buy from them again.

This item is very good. and fast delivery. Thank you very much

Did the job & no leaks!
