To prevent contamination, these couplings are cleaned, double bagged, and packaged in a clean room. This makes them a great choice for applications where cleanliness is critical, such as semiconductor manufacturing. Known for their versatility, they fit any luer lock plug, socket, syringe, or needle. They’re quick to attach and detach, so they’re often used in lines that are frequently disconnected. Thanks to their compact body, they fit in tight spaces. Use them in low-pressure applications.

Note: For a complete coupling, order a plug and a socket.

Barbed couplings securely grip tubing and hose.

Nylon couplings have excellent impact and abrasion resistance. Use them in general purpose applications. Polyolefin couplings are BPA-free and autoclavable. Polypropylene couplings resist moisture and chemicals, including solvents. They also stand up to impact and abrasion.

Plugs with a locking ring are more secure than those without a locking ring. Give the ring a half turn to lock them in place. You can’t remove the locking ring.

Plugs without a locking ring are quicker to install and remove than those with a locking ring. Also known as luer slip plugs, all they need is a light push to secure. Add a snap-on ring (sold separately) to lock the coupling in place and color code your line.
