Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring or sleeve and pull the tubing out of the fitting.

Fittings with release sleeve are easier to disconnect than fittings with a release ring because they are seamless and won't collect dirt and debris.

Metric and UN/UNF (SAE Straight) male threads with gasket or thread sealant provide extra protection against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

NPTF (Dryseal) threads are compatible with NPT threads.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect fittings with a release ring, push on the release ring and pull the tubing out of the fitting.

Acetal fittings resist moisture, so they won’t soften and lose strength in humid environments. They meet NSF/ANSI 51 for safe use with food and NSF/ANSI 61 for safe use with drinking water.

Black fittings have excellent UV resistance and are suitable for outdoor environments.

Made of moisture-resistant acetal, these fittings won't absorb water and lose strength, even in high-humidity environments. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. All meet NSF/ANSI 61 for use in drinking water systems.

BSPP male threads have a gasket to protect against leaks.

Create a push-to-connect junction between tubing and unthreaded ports in your equipment. As an alternative to installing a threaded port, insert these fittings in equipment such as taps, manifolds, and flow direction splitters. Also known as instant fittings, they have a grasping ring and O-ring that hold your tubing in place, and a release ring that disconnects it. Made of moisture-resistant acetal, these fittings won’t soften and lose strength in high-humidity environments. They meet NSF/ANSI 61 for use in drinking water systems and NSF/ANSI 51 for use with food. Use them in low-pressure applications.

To install, drill a stepped hole in your surface using tools such as a CNC machine or lathe. After removing all debris and burrs from the hole, push the fitting components into place. Then insert your tubing until the tube end is flush against the tube stop. To disconnect, push on the release ring and pull the tubing out.

Create a strong connection without heating, flaring, or soldering. These fittings have a single sleeve (ferrule or olive) that bites into tubing as you tighten the nut. Both the nut and sleeve are included. Also known as single ferrule fittings, they are easier to install than yor-lok fittings which have two ferrules. They’re often used in low to medium pressure applications, such as plumbing and compressed air systems, which don’t require the strength of a yor-lok fitting. Compression fittings for copper tubing can withstand higher pressures than compression fittings for plastic and rubber tubing. Made of brass, they have good corrosion resistance.

To connect a compression fitting to tube, slide the nut and sleeve onto the tube. Then push the tube into the fitting until it butts against the back of the fitting. Tighten the nut onto the fitting to compress the sleeve.

Threaded connections can be taken apart as needed for maintenance and repair.
