Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand acids, solvents, and other harsh substances.

The inside of these fittings won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes it easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC fittings.

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

Made of acetal, these compression fittings are lighter in weight than metal compression fittings and won’t absorb moisture when used in wet environments.

Made of plastic, these couplings are lighter in weight than metal luer lock couplings. They're a popular choice in labs because of their versatility—they fit any other luer lock plug, socket, syringe, or needle.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.

These plastic compression fittings meet NSF/ANSI Standard 51 for food contact.

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 140 psi.
