Imperial Tool 17C Kwik-Coupler Adapter 90 Degree Elbow Coupler 45 Degree Flare, 1/4"

I have been using the 1/4" version of this kuik coupler for many years with 100% satisfaction. This time my need was for 5/15" adapter for R410a. It would have been nice to be able just a 5/16" attachment instead of buying the whole unit.You would not regret this purchase.

So i took a chance on this product, here is a video of us using it at trade school the FIRST time. Nobody knew what this thing was. So far we like it tho you can see we didnt do a perfect job on the first try, i think this tool will prove to be a better alternative to the sealright fittings: only time will tell, i will update review after a couple months of use.

Generally they work great. Do have some problems with them, but they are easy to remedy or work around. Sometimes refrigerant will leak between the nut; so I tighten the insert on the o-ring. Occasionally refrigerant sprays through the threads on the nut; then I tighten it a tiny bit more with pliers. Finally, once in a while the internal valve does not open fully which effects the pressure reading, but it will read correctly if I push the hose end of the quick connect body away from the side with the clip. Also, they don't work with king valves and I don't use them when evacuating the system. I realize that this may seem like a long list of issues, but all the other low-loss fittings I have used either release more refrigerant or have a much shorter effective life.

Works great! I got some extra o-rings just in case but I haven't needed them yet. I'm pretty new to HVAC and the first type of low loss fitting I got leaked. So I tried to use my gages without one and of course got burned. A lot of the more experienced guys had this style so I picked one up and haven't burned my fingers since.

Seals up good.

very good quick coupler. very handy to avoid excessive refrigerant leakage.

I work in HVAC and I use my Bluetooth gauges every day because I work in service. I was super happy when I received these in the mail. A friend recommended these. I tried one...perfect! The second... too big! I checked my order to see if I ordered wrong but I didn’t. Please fix this and I will change my review to 5 stars because I truly do like them. I have low loss fittings but doesn’t com close to these in regards to speed and efficiency. Thank you

You have to be careful with this as it causes inaccurate readings some times (it doesn’t fully depress some cores properly, always verify with a second set of gauges if you think the pressures don’t look right or good). It works well for attaching in tight spaces though and for that reason it’s been an invaluable tool. I was thinking this was a push connect style but it does still require you to screw on the cap before pushing it on (this cap does not like to thread right every time so pay attention to that). It does leak sometimes. I have this on my quick check gauge but WOULD NOT RECOMMEND FOR YOUR REGULAR GAUGES.
