Water/Air Silicone Tubing – 10.5 mm OD × 7.1 mm ID

This flexible silicone water and air tubing provides a practical replacement solution for compatible CO2 laser engraving and cutting machines. Featuring a 10.5 mm outer diameter (OD) and 7.1 mm inner diameter (ID), it is suitable for air and cooling-water connections where the tubing dimensions and operating requirements match.

Commonly used for connecting cooling-water lines to compatible CO2 laser tube glass fittings, this tubing is listed for certain 30–60W laser systems. Its flexible silicone construction allows convenient routing around internal machine components. Sold by the foot, it provides an easy way to purchase the length needed for maintenance, repairs, or replacement.

How Water/Air Silicone Tubing Works

CO2 laser machines depend on properly routed tubing to transport air and cooling water between system components. Cooling-water lines circulate water between the laser tube and cooling equipment, while air lines deliver airflow to compatible air-assist systems.

This silicone tubing features a 7.1 mm internal passage that allows water or air to move through appropriately sized connections. Its flexible construction helps accommodate bends and changes in direction while routing between machine components.

Proper tubing selection is important for maintaining reliable airflow and cooling-water circulation. Incorrect tubing dimensions, loose connections, or restricted flow can affect machine performance and may lead to equipment damage.

CO2 Laser Tube Cooling and Air Applications

Laser Tube Cooling: This tubing is commonly used for compatible water connections on certain 30–60W CO2 laser tube systems. When properly matched to the tube's glass fittings, it provides a flexible connection for circulating cooling water.

Air Supply Connections: The tubing may also be used to route air between compatible compressors, fittings, and laser machine components when operating pressure and material requirements are suitable.

Not all CO2 laser tubes use identical glass fittings, even when their wattage ratings match. Always confirm the actual fitting dimensions before selecting tubing for your laser's cooling system.

Choosing the Correct Tubing Size

Rabbit Laser USA offers several silicone tubing sizes for different air and water connections. This 10.5 mm OD × 7.1 mm ID tubing has a larger internal passage than our 9.1 mm OD × 6.14 mm ID and 6.5 mm OD × 3.6 mm ID silicone tubing options.

Larger internal tubing diameters can accommodate greater flow under comparable conditions, but actual air or water flow depends on the pump, compressor, fitting sizes, tubing length, and the rest of the system.

The correct replacement should match both the inner and outer diameters required by your equipment. Different tubing sizes are not automatically interchangeable, particularly when connecting to delicate glass laser tube fittings.

Confirm Compatibility Before Ordering

Before purchasing replacement silicone tubing, compare the following specifications with your existing equipment:

• Existing tubing inner and outer diameters
• CO2 laser tube glass fitting dimensions
• Compressor outlets, hose barbs, and connector sizes
• Required tubing length and routing path
• Air or water pressure requirements
• Operating temperature and material compatibility

A matching laser tube wattage alone does not guarantee compatibility. Confirm the actual fitting dimensions before ordering. Specific pressure and temperature ratings have not been established for this tubing, so suitability for demanding applications must be verified.

Installation & Safety

Before replacing tubing, turn off the laser machine and connected air or water equipment. Release system pressure and drain water where necessary. Cut the tubing cleanly to the required length and install it using properly sized fittings and any necessary retainers.

When connecting tubing to glass CO2 laser tube fittings, avoid excessive force, twisting, or pulling that could damage the glass. Route tubing away from heated surfaces and moving components, and prevent sharp bends or kinks. After installation, inspect connections for leaks and verify proper cooling-water circulation or airflow before operating the laser.
