I broke this small part while changing the filters on my ro. I was worried I would have to buy an entire new system. This part fit and worked great. I have been using it for over 6 months with no issues.

First one Amazon sent had a cut across the little zip lock bag APEC ships this in and the part fell out I am guess long before Amazon shipped it to me so I received an empty bag. Amazon quickly resolved within hours of me sending email and even paid the next day shipping on the replacement part.With the faucet off I could hear water draining in my sink was the tip off something was wrong. Took 5 minutes to change this part due to quick connect fitting. Complete instructions are included with the part. I put some teflon tape on the threaded end per the instructions. I must not have gotten the water tube seated fully because when I turned on the water I got wet quickly. Turn water back off at supply and tank and reinserted the line and gave it a second shot. Days later no leaks and I no longer hear water back flowing from the holding tank.
