SharkBite Prolock One IN. Push-To- Connect Plastic Coupling Fitting Is; The most user-friendly-simplest and most dependable fittings on the market. No tools are required to make a connection. The stainless steel teeth really hold with a very tight grip. My project calls for PEX Piping due to many turns through studs. Although not very complicated, the project requires routine moving of piping. This fitting is perfect. Changes can be made instantly. The only tool required is the pipe cutter for new pieces. This fitting once fully inserted, is permanent, and leak-proof seal. The Twist-to-lock technology ensures maximum security.

With this SharkBite prolock 1" coupling. It is easy to use and will hold up anywhere in the water line. Used on PEX line will hold and not leak. After installing give the locking sleeve a twist. Twist till you hear the click. This will lock the clamping tabs onto the PEX to hold tight and not slip off or leak. I tried pulling on the coupling and could not budge it.

Extremely easy to install. If necessary, it is also a snap to remove. No extra tools are need to install or remove. Unlike the brass Shark Bite, you do not need the horseshoe shaped plastic decoupling tool, which I have laid down several times on a work site and because it is so small, it is sometimes hard to relocate. So, with this coupling, there is no need to worry about losing the decoupling tool. I would have given it five stars but I am not convinced it will be as rugged as the brass Shark Bites couplings. Only time will tell. Another plus is that this plastic coupling is about half the cost of the brass equivalent.

The SHARKBITE PROLOCK 1/2 IN. PUSH-TO-CONNECT PLASTIC COUPLING FITTING (8-PACK) These SharkBite 1/2 in. couplings are great to keep hooking up your PEX or PERT water lines. You can also fix a leak in a water line with these, by cutting out the spot that leaks, and just install one of these couplings ! As long as the repair is not longer than the coupling itself. The SharkBite ProLock's need no tools, and all you do to install, is push your water line in one end, and twist to lock, and your all set !! Get some and try them, you won't go back to the old conventional way of plumbing !

The design of these plumbing fittings has been evolving for many years, and I think this may be the best I've seen. So easy to work with, it takes the guess work out of installation. The key is to be certain your pipe is cut square and smooth as the fittings use a sealing o-ring to prevent leaks. By pushing the pipe in until it clicks and turning the collar a quarter turn, you have created a solid seal that won't leak.

When using the Shark Bite Pro-Lock 3/8" straight Coupling. It's the easiest way to join up two separate pieces of 3/8" piping. The Pro-Lock connectors are easy to use. All you do is insert the pipe into one end of the coupling then you turn to line up the arrows which will then lock the pipe to the Shark Bite Pro-Lock coupling. To remove simply turn the arrows apart. Press the ring on the end and slide the pipe out. Shark Bites have changed the way plumbing is done.

I'm building a series of temporary raised flower beds and setting up a watering system. The sharkbite fittings look like just what I need. In my photo you can see that I started using brass fittings. A tool is needed to uncouple the brass fittings were as this pro lock fitting has a very handy feature, you insert the tubing like normal but then there's a locking ring that you rotate to lock the fitting on to the tubing. So doing the reverse and decoupling is simple. The fittings are also less expensive than the brass ones.
