Also known as I-line fittings, these fittings have a male adapter that interlocks with a female adapter for more support than standard quick-clamp fittings.

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools.

For use in high-vacuum systems, these fittings use a metal reinforced O-ring to create an airtight seal. Also known as KF, QF, and NW fittings, they’re used for high-vacuum applications such as vacuum coating and heat treating, leak testing, and analyzing gases.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Designed for use in welding applications, these fittings are flame retardant.

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 spring-free flow path allows more air or water to pass through these tube couplings at lower line pressures than other quick-disconnect 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.

These fittings keep their strength in moist environments and meet NSF/ANSI 61 for drinking water. Also known as instant fittings.

Create corrosion-resistant connections in food and beverage lines with just a push. Also known as instant fittings, these fittings have an internal gripping ring and an O-ring that hold tight to tubing.

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.

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.
