By far the easiest to use out of any brand
Best quick connects on the market! I Have used several different brands in the past and these are by far the easiest to use. Most connects that I've used in the past are pain and almost not worth the hassle.

Great time saver for setting up. Highly recommend!
I use these couplers for my torch setup on my service truck. They have been holding up great. They are a great time saver for setting up, and being able to switch from one torch to another in a matter of seconds, without the need to turn off the gas bottles. Would highly recommend.

Get these quick connects, you won't regret it!
Very high-quality product and the best one on the market. Not only does it make connecting and disconnecting the hoses faster and easier, but it also allows hoses to spin in place freely when attached which makes everything even better. I recommend anyone and everyone who’s using a torch to get these quick connects. you won't regret.

Know hundreds of welders who have them
I weld on pipeline and know hundreds of welders who have them. Outside in the mud, rain, salted roads, extreme heat, replaced one after 10-12 years of daily use. By far the best ; and I’ve used the brass and aluminum knock offs and they will fail in shop like conditions. You get what you pay for……. Koike is the only one I’ll buy…..
