It is easy to install, no tools or tube inserts are required. The fitting can be used for hot and cold water applications. The unique O-ring guide feature provides a zero-leak connection. Unlike barb fittings, this fitting joins the tubing on the outside, increasing the flow capacity. After a connection has been made even under maximum pressure, the tubing is able to swivel, making the fitting ideal for vibrating and dynamic applications. From the Manufacturer This fitting incorporates stainless steel gripping teeth in the collets. These corrosion resistant teeth allow the connectors to interconnect with multiple materials without the need for special tools. It works with copper, CPVC, and PEX (LDPE, MDPE, HDPE) tubing. Review: Give these people their patent! - I'm really dangerous when it comes to plumbing - really dangerous. I needed to install a new tub faucet. I ordered a faucet, got a couple of pieces of Pex, some tape, and a few Sharkbite elbows. 2 out of the 3 Sharkbite elbows seemed to connect fine onto the plastic threads of the faucet. The 3rd wouldn't do anything but cross-thread which noticeably damaged the threads on the faucet. I went to Lowe's to get another faucet and also look for some other way to connect the waterline with something other than the metal Sharkbite elbow. The only thing they had was an elbow that had to be connected with a crimper which just seemed...out of my league and definitely outside my toolset. Being hardheaded, I picked up a new faucet and decided I'd be really careful not to cross-thread it this time. No matter how careful I was, it cross-threaded anyway. I decided to get on desertcart and see if anyone made a Pex to Faucet elbow that was plastic. Honestly I would have thought Sharkbite would have made something (that didn't require a crimper), but was surprised to only find this little elbow. I am thrilled to say this worked like a charm! It screwed onto my faucet with ease and not even the least bit of threat of cross-threading. It says the patent is pending and all I have to say is give these folks their patent! Very thankful for someone's invention and being able to file this project into the done category. Already ordered 3 more for my next faucet replacement project. 10/10 will definitely eat here again.

It’s the gray tubing found in most older mobile homes** A: That's exactly what I use it for and it works great. **Q: The description says it will work on polybutylene pipe.. My package has no mention of polybutylene pipe. My package part number is 3520-1008 not959090** A: It should work if the size is correct.

Thanks!** A: This is used in conjunction with PEX tubing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Give these people their patent! *by Z***K on April 10, 2023* I'm really dangerous when it comes to plumbing - really dangerous.
