2.5mm Hose | McMaster-Carr

To protect sensitive equipment, this tubing is made of nylon that’s specially formulated to let currents pass through, preventing static electricity buildup. It’s often used as a safeguard in pressurized air systems. Comparable to UL 94 V-0, the material is flame resistant and delays the spread of flames. It’s opaque, so you cannot see inside.

Made from PFA plastic, this tubing keeps condensation from forming by diffusing water vapor. It’s often used with air cylinders, air-operated valves, and other compressed-air equipment. Steel supports inside the tube ends keep the tubing from collapsing, so you can create a strong seal with push-to-connect fittings. Tubing is clear so you can monitor flow inside the line. Over time, the color will change to brown, but this does not affect performance. Tubing dimensions may vary slightly based on the temperature and humidity of the environment.

Straight tubing is more rigid than coil tubing, so it’s used for gradual bends. It’s often paired with stationary equipment.

Coil tubing has tube ends that face the same direction, so it’s used for sharp bends. It’s often used to connect moving parts.

Inline coil tubing has ends that face opposite directions. It’s used to make inline connections between straight tubing and components that rotate.

Note: Do not cut tube ends or remove tube supports.

Welded Stainless Steel Tubing

Straight

When your application does not require a smooth interior, this tubing is an economical choice. It has a weld bead on the inside.

304 stainless steel has very good corrosion resistance.

316 stainless steel offers excellent corrosion resistance.
