Color: Gray
John Guest Part# : PI010823S
Tube O.D.: 1/4"
Thread NPTF: 3/8"

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.
Disconnecting
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.

In 1961 John Guest`s vision was to run a company with innovation, quality and sustainable growth to be at the core of the organization’s principles.

In 1974, John Guest developed his first push in tube connector for use with compressed air. That basic "Super Speedfit" concept has been developed to include fittings for a wide range of applications.

John Guest`s World Headquarters are located in the UK where all their fittings are designed, manufactured and distributed throughout the world.

Thread Size Not 3/8

The 3/8 in the product description is misleading. It is not a 3/8 thread size. I think that the thread is 5/8. Of course, I don't have a tap that large. GGRRR… A little more thought and I would have realized that 3/8 is the ID.
