SharkBite Straight Stops combine push-fit technology with a straight stop quarter turn valve. This allows the valve to control water flow to household plumbing fixtures, and provides easy shut-off of water flow for maintenance and repair, if necessary. These valves require no solder, clamps, unions or glue. The push-to-connect end allows you to push on to Copper, PEX, CPVC or PE-RT pipe easily. This product can be easily rotated after assembly for easy installation, even in tight spaces.

Rated 5 out of 5 by from Works Great, Slips on Easy, Perfect for Icemaker Connections These quarter turn valves work great for hooking up things like icemakers. Icemakers usually need 1/4" supply lines and this valve fits the need perfectly. I have this pushed onto 1/2" CPVC pipe, and then connected to a braided steel line to the icemaker. I can shut down the icemaker water supply to move the fridge with just a quick quarter turn of this valve. It works smoothly and easily. These Shark Bites allow you to make fast, clean, quick installations of shut-off valves in tight areas. I have used these for quite a few connections that needed shut-offs and they always work great. I will continue to use them whenever I can.

Rated 5 out of 5 by from Unbelievably Good I have worked with all known types of plumbing for forty years (brass, copper, steel, ceramic, rubber, glass, miniature, PVC, medical equipment, housing, ranch, irrigation, etc., etc.) except PEX pipe. I had no faith whatsoever that a simple replacement of a PEX valve in a manufactured house would be a quick drip-free job. Wow was I wrong! The Sharkbite valve slid on easily, and surprisingly enough the seals actually work. I installed three valves in a bathroom over a month ago, and all three have worked perfectly. I am so pleased with Sharkbite that I now think that for my next re-plumbing of a house I might choose PEX and Sharkbite valves. No glue, no Teflon, no goop, no heat, no solder, no wrenches, no strain, just cut the pipe and slide the valves on; unbelievably easy. Sharkbite saved me days of re-plumbing, and I'd give it one-hundred stars if I could.

Rated 5 out of 5 by from I'm Sold! So I was in the process of installing a new faucet in an 85-year-old house and realized that there were NO shut-off valves anywhere to the copper water pipes leading upstairs, save for the main house shut-off. I'm not a plumber by any stretch, and when the guy at Home Depot suggested Shark Bites, I was a bit skeptical. But I have to rave-- these things work like a charm!! Simply cut the pipe (leave at least 1.5" for the Shark Bite to slide over), hit the pipe with an emory cloth 'til it's shiny and burr-free, slip on the Shark Bite and you're done! Amazing! And it doesn't leak a drop!

Rated 5 out of 5 by from Great for DIYers Push-to connect valves might seem expensive, but they're cheaper than a plumber and allow DIYers who aren't comfortable with soldering an opportunity to do some plumbing upgrades. They're also great when you have a main shut off valve that doesn't fully shut off which can make soldering difficult. I used my first first push-to connect valve over 6 years ago and it's still working perfectly. Also, I love the quarter turn stop valve, it's the only type of valves I utilize. Much better quality and longer lasting vs the older multi turn valves. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Sooo easy and awesome! We have cpvc water supply lines. Had to replace the shut-off valve to the toilet because it was hissing. Originally, the shut-off valve was a compression solder weld with a multiturn handle. I wanted a 1/4 turn. The Sharkbite was so easy to install. I used a circular copper pipe cutter to cut the cpvc just below the weld and pushed the SharkBite on until it clicked and couldn't go any further. Not a drop of water leaks and it took me a total of 5 minutes...the longest part being cutting the cpvc pipe!!

Rated 5 out of 5 by from Easy for anyone to use! Best way to connect new plumbing! No soldering or torches just click it in and go! Dont forget to buy the release clip for these fittings though, a life saver! A++

Rated 5 out of 5 by from So easy ! I had to install a new supply line for a toilet and used the Sharkbite system with PEX pipe. Take it out of the box and push it onto the pipe. Done. Really as simple as that. It could not possibly be easier.

Rated 5 out of 5 by from Works great! I recently upgraded my kitchen faucet and in doing so realized the old valve needed an upgrade too. This thing works great! I simply cut the pipe, slid this thing on and connected the new water line. Very easy to install! If you are cutting the pipe make sure you have atleast an 1" to work with as this valve needs about that much to work correctly. I definitely recommend the sharkbite and will be using these for more valve replacements in the future.

Will this part (1/2" X 1/4" COMPRESSION STRAIGHT STOP #23337-0000LF) work on 5/8" outer diameter copper pipe under my sink? Maybe my 5/8" OD pipe has an 1/2" ID and interior diameter is what you use to label the part compatibility?

Asked by: RogerB
Good afternoon, All our SharkBite products are sized and labeled according to copper tube size. Copper Tube Size is based off ID of the pipe. As long as you have Copper, PEX or CPVC and the ID of the pipe is 1/2", you can use our 1/2" fittings.

Do you make a 3/8 x 3/8 fitting? If not, is this something you may manufacture in the future?

Asked by: leej

Do you have and angled stop valve that will push onto 3/8" od copper and have a 1/2" comp. fitting or 1/2" mip connector on the other side?

Asked by: Moose
Good afternoon, If the Copper pipe is hard drawn Type K, L and M and annealed Type M not to exceed 3/8 nominal, complying with ASTM B88, 3/8 OD pipe should be 1/2 inch copper pipe. You can use our standard 1/2 inch x 1/2 inch threaded connector: U120LF.
