JG 1/4 inch x 1/4 inch Union Ball Valve Information

Some valves are made with poor quality that they start leaking on your first day of use, but you never have to worry about this with the JG Union Ball Valve from Pet Store. This product guarantees quality for your money. Most valves in the market tend to be extremely difficult to turn after quite some time but this product’s sturdy, easy-to-adjust feature sets it apart. This high-performance valve can absolutely hold pressure even after multiple disconnections. This product connects into ¼ inch tubing. The white-colored, lightweight union ball valve that is 0.5 ounces assures you of excellent functionality.

This product is super easy to connect and remove. To make a connection simply cut the tube square, then insert the tube. Afterwards push up to tube stop and then pull on the tube to check a secure fit. See, it’s as easy as one, two, three!

John Guest (JG) has been in the industry since 1961. With the long-time experience in innovative and quality products together with the birth of its Super Speedfit technology, there is no room left to doubt about the superiority of this product.

Say goodbye to leaks and hello to hassle-free connection with the JG Union Ball Valve. Buy one today and see the difference!

Color: White
John Guest Part# : PPSV040808W
Tube O.D.: 1/4"

How to make a connection:

  1. Cut tube square.
    Cut the tube square. It is essential that the outside diameter be free of score marks and that burrs and sharp edges be removed before inserting into fitting. For soft or thin walled plastic tubing we recommend the use of a tube insert.
  2. Insert tube.
    Fitting grips before it seals. Ensure tube is pushed in to the tube stop.
  3. Push up to tube stop.
    Push the tube into the fitting, to the tube stop. The collet (gripper) has stainless steel teeth which hold the tube firmly in position while the "O" ring provides a permanent leak proof seal.
  4. Pull to check secure.
    Pull on the tube to check it is secure. It is good practice to test the system prior to leaving site and/or before use.
Push in Collet and remove tube.
To disconnect, ensure the system is depressurized before removing fitting. Push in collet squarely against face of fitting. With the Collet held in this position, the tube can be removed. The fitting can then be re-used.

Comments: It's really hard for anything wrong to be with a valve, but some of them are made so cheap they start leaking on the first day. This one is very sturdy and holds pressure after multiple disconnects.

Comments: John Guest valves seem to be one of the best valves available for the price. On most valves, they are difficult to turn after time. These valves continue to operate easily.

Comments: These ball valves were talked up so much I expected them to last at least 6 months. Not the case- now granted, I have been using them regularly to top up evaporation (not their intended use). Regardless, I wish that they would have lasted longer considering their astonishingly high price. Two have failed on me in a matter of months. it is now plainly clear to me that they have a very limited life. on the plus, they are easy to set up and functional (before they fail).

Comments: I have probably purchased 5 or so of these devices. It works great with no leaks and it's extremely easy to connect to flexible tubing. I am a big fan of speed fit which saves time, but I was worried about leaks. Purchase with confidence, so far no leaks. I wish they were a little cheaper, but that's about the only "relative" con I can find. My setup includes these union ball valve at: Source water, after RO product water, and after DI product water. Makes it very easy to control.
