John GuestSpeedfit 5/16 Inch OD Union Connector, Push to Connect Plastic Plumbing Fitting, White, NC2112P

Common size for refrigerator icemaker lines from filters under units. Worked well no problems

This coupler worked perfectly in my refrigerator. A lot cheaper than a repairman. Just get the right size.

Was supposed to get two on this order but only one in the bag. The product is easy to use and appears to work.

It worked immediately and properly. I am astonished to see how many people have repaired plastic tubing that sprung leaks on the backs of refrigerators, and there are two separate brands of products to fix this leaky tubing. I had thought plastic tubing is better than this.

My fridge water line sprung a leak so I got this little gizmo to fix it. Too a couple of tries, but works like a charm. The key, as others have mentioned, is the cut of the tubing has to really be straight. If it is cut at an angle the seal will not be good and it will still drip.

Had a plastic water tube on refrigerator that broke. Bought this item, pushed one end on one tip of the line, pushed other end onto other end of the line...perfect fit. No leaks. Great item

Easy push to connect. 5/16" poly tube.

I bought this coupling to retro fit an Italian Expresso machine that my customer needed to allow for water source from the stock reservoir but also be able to easily convert to inline water supply for a mobile coffee cart. The manufacturer sold a conversion kit but that would only work for the inline supply once installed and my client wouldn’t have been able to easily convert back. With the coupling we avoided the conversion kit and customer can now quickly change back & forth in minutes to suit her needs.
