JG 1/4 inch x 1/4 inch Bulkhead - Grey Information

Color: Gray
John Guest Part# : PI1208S
Tube O.D.: 1/4"
Tube O.D.: 1/4"

How to make a connection
  1. Cut 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: These John Guest bulkheads are some of the best and easiest to use. They are easy to install and don't seem to leak at all. I've installed a few in my RO and top off system and haven't had a problem. I would recommend this product.

Comments: For its intended use, I'm sure this part is great. How could JG not be?However, it is NOT intended for the use that it appears most people are trying to use it for.I came by the website to look for something like this for an auto-topoff system. Doing a little more research elsewhere, I found John Guest's catalog, which specifically states that this bulkhead is not for submerged use. So, it's not designed to be at the bottom of a trashcan-reservoir for ATO purposes.

Comments: I drilled a 5/8 in. hole in the side of a 5 gallon bucket near the bottom and installed this in it,connected(with 1/4in. tubing like is used for RO/DI filters)to a Kent float valve in my sump for auto top off,I set the bucket on a table next to my sump for gravity flow,it works great. I did add 1.5 to 2 gallons a day,now I just fill the bucket every other day. My water level in my sump hasn't changed since I did this. I would have gave it a 5 star rating if it had came with a rubber gasket.
