    John Guest 1/4"JG x 3/8"COMP Female Compression Fitting - PP6008U9W

    The John Guest 1/4 in. O.D. x 3/8 in. Push-to-Connect Female Compression Connector (10-Pack) fittings are manufactured from white polypropylene and equipped with EPDM O-rings utilizing John Guest's push-fit technology to make easy, reliable, leak-free connections. They have been developed to satisfy the compatibility needs for a wide range of applications and can be used on plastic or soft copper tubing. To make a connection, the tube is simply pushed in by hand; the unique John Guest collet locking system holds the tubing firmly in place. Disconnection is just as easy and requires no special tools.

    John Guest 3/8"JG x 3/8"COMP Female Compression Fitting - PP6008U9W

    Push-fit plastic fitting for the connection of plastic, copper, and CPVC pipe. Designed, manufactured and assembled by John Guest Speedfit. Simply push the fitting fully onto the pipe and twist the plastic nut clockwise to lock in place. Should the need arise to demount the connection unlock the nut and push the collet towards the body of the fitting and pull the pipe to release. The fitting ensures an easier working environment in confined places, is approved for behind the wall installations, and removes the need for hot works on site. Installation can be reduced by around 40% when compared to traditional fixing methods.

    How to make a connection:

    * 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.
    * Insert tube
    Fitting grips before it seals. Ensure tube is pushed in to the tube stop.
    * 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.
    * 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.
