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.

To prevent contamination, these couplings are cleaned, double bagged, and packaged in a clean room. Known for their versatility, they fit any 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.

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.

Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Fittings resist acids, solvents, and other harsh chemicals. They won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.
