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.

Use these luer lock couplings to quickly connect low-pressure air and water lines. Made of stainless steel, they’re more durable than plastic couplings.

A staple in labs, these couplings are highly versatile, fitting any luer lock plug, socket, syringe, or needle. They’re PVDF, so they resist most acids, alcohols, and organic solvents.
