Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser.

Use these nuts with compression sleeves and fittings to create a strong seal on stainless steel tubing.

Tighten these nuts onto high-pressure compression sleeves and fittings to create a strong seal on stainless steel tubing.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

The flat face of the fitting connects to a tube adapter so you can slide the tubing and fitting sideways to disconnect in cramped spaces. They are also known zero-clearance fittings.

Use at pressures up to 1,500 psi.

Connect stainless steel tubing on one end and plastic tubing on the other end.

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

Transfer liquids and gases into high-vacuum chambers with these assembled fittings, also known as feedthroughs. Their quick-clamp (ISO-KF) connections are easier to install and remove than bolt-on flanges.

Connect high-pressure brake lines with fittings that won’t crack in frigid temperatures. Often used on commercial trucks and trailers, these fittings meet Department of Transportation FMVSS 571 safety standards.

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.

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.

Use these nuts and sleeves with compression fittings for food and beverage to create a seal on plastic tubing.

Fittings are 316 stainless steel, which has excellent chemical resistance and is more durable than plastic.

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.
