Reinforced Vinyl Water/Air Tubing – 13.75 mm OD × 9.4 mm ID

Laser Machine Tubing & Hoses

Reinforced Vinyl Water/Air Tubing – 13.75 mm OD × 9.4 mm ID

This reinforced vinyl water and air tubing provides a durable solution for compatible CO2 laser cutting and engraving machine cooling and air-assist systems. Featuring a 13.75 mm outer diameter (OD) and 9.4 mm inner diameter (ID), it is particularly useful for external cooling-water connections between a laser machine and its water chiller.

Unlike standard unreinforced tubing, its reinforced construction helps resist expansion and deformation under appropriate operating conditions. It can also be used for compatible higher-pressure air-assist applications when the system's pressure requirements fall within the tubing's verified ratings. Sold in 3-foot sections, this tubing provides a practical option for replacing worn or damaged external water and air lines.

How Reinforced Vinyl Tubing Works

CO2 laser machines require reliable connections between their cooling equipment, air supplies, and internal components. Water tubing circulates cooling water between the laser machine and its chiller, while air tubing transports compressed air to compatible air-assist systems.

Reinforced vinyl tubing contains an additional reinforcing structure within its walls. This reinforcement helps limit expansion and deformation when the tubing is subjected to pressure, making it useful in applications where additional hose support is desired.

This tubing features a 9.4 mm internal passage and is intended for use with appropriately sized fittings. Proper tubing selection, secure connections, and operating within the manufacturer's pressure and temperature limits are essential for reliable performance.

Laser Chiller and Air-Assist Applications

External Water Chiller Connections: Reinforced vinyl tubing is particularly useful for connecting compatible laser machine water inlet and outlet connections to a separate water chiller. Its reinforced construction provides additional resistance to hose expansion during normal operation within its rated limits.

Air-Assist Systems: This tubing may also be appropriate for certain higher-pressure air-assist applications. Reinforced hose construction can be beneficial where additional resistance to expansion is needed, provided the tubing has a verified pressure rating suitable for the equipment.

The correct tubing depends on the operating pressure, temperature, required flow, and connection dimensions. Reinforced construction alone does not establish a specific maximum working pressure.

Reinforced Vinyl vs. Silicone Tubing

Silicone tubing offers excellent flexibility for many internal laser machine air and water connections. It can be particularly convenient when routing around components or working in confined areas.

Reinforced vinyl tubing provides additional structural support within the hose wall. This can help reduce expansion under pressure compared with similar unreinforced tubing, making it a useful option for compatible external water lines and air-assist applications.

Neither material is universally better for every installation. Select tubing based on the required inner diameter, operating pressure, temperature, flexibility, and connection type. For higher-pressure applications, always confirm the manufacturer's working pressure rating before installation.

Confirm Compatibility Before Ordering

Before purchasing reinforced vinyl tubing for your laser machine, compare the following specifications with your existing equipment:

• Existing tubing inner and outer diameters
• Water chiller inlet and outlet fitting dimensions
• Laser machine water connection and hose barb sizes
• Air compressor outlet and air-assist fitting requirements
• Operating pressure and temperature requirements
• Required tubing length and routing path

A matching tubing diameter alone does not guarantee compatibility. Confirm that the fittings and operating conditions are appropriate before ordering. This tubing is sold in 3-foot sections; multiple quantities should not be assumed to arrive as one continuous length.

Installation & Safety

Before replacing tubing, turn off the laser machine and connected air or water equipment. Release system pressure and drain water where necessary. Verify that the tubing fits the intended connections and secure it using appropriately sized fittings and any required hose clamps or retainers.

Route the tubing to avoid sharp bends, excessive tension, heated surfaces, and moving components. After installation, inspect all connections for leaks and verify proper water circulation or airflow before operating the laser. Never exceed the tubing's verified working pressure or temperature limits.
