Joywayus Brass 1/4" NPT Female Thread Push Button Check Valve Switch Shut-off Valve

UPDATE: After inspecting more I noticed that there appears to be a rubber o ring inside this valve. While this would suffice for most, I can not use it because I bought it to add hydraulic fluid to an aircraft landing system, and some rubber orings will disintegrate upon contact with this type fluid. Therefore, I am sending it back. I still think it is an excellent product but just won't work for my application. ==== It says it’s a check valve and has an arrow on the side, but it’s not a check valve as you nan blow thru it from either side. It makes no difference to me as I don’t need a check valve.

Clean and easy install with push connectors. Much better than pic-nik valves. We use this many many times a day no leaks smooth one handed operation. Installed on flexible coil air line that really makes the entire project easy to use.

I’m using this on an air line with about 120 psi of pressure. When I first connected it, I hadn’t paid attention to the little arrow stamped into it. The result was my initial disappointment because it wasn’t completely sealed and was letting air through. I then saw the arrow and tried installing it with the flow in the correct direction and it works great!

Does not work as an air bleeder. I thought it would because someone posted a picture of them using it with a Presta valve to air up their bike tires. This is the top search result for 1/4 NPT push button bleeder. This is only used to control air flow going into something (air tank, tire, etc.), but you would have to have a fill gauge to know the what pressure inside is, or use a separate air gauge to measure pressure inside. Edited 11/28/2022 rating from 3 stars to 5 stars as it works as expected as a check valve.

I used this combined with fittings to do pressure checks for water fittings on injection molds. Air lines in our shop are usually around 110 to 120 psi. This is still holding up after many many uses.

Good product and well built. This push button is being used in a custom built water dispenser for 5 gallon water bottles running at 60PSI. By using a pump that turns off at 60PSI and on at 40PSI this button is used to allow the water to flow when pushed. I have a mechanical pressure gauge installed inline and after 4 hours there is no pressure loss and no leakage when in standby or while being used. i have tested several push buttons and this one has functioned flawlessly. I highly recommend this product.

Used it on a car lift works great

Have purchased this valve before using it in several projects, works well, very durable and very quick shipping
