    Insert tubing into these fittings and an internal gripping ring and O-ring hold the tubing tight. They are also known as instant fittings. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings have good corrosion resistance. Use them in low-pressure applications.

    Identification rings (sold separately) snap over the release ring so you can color-code your lines.

    Clips (sold separately) align and organize your tubing and fittings.

    Fittings with PTFE thread sealant offer extra protection against leaks.
