What This Rigging Hose Union is Used For

The TUNION provides a simple connection point between two pieces of 2" outboard rigging tube.

Common uses include:

• Extending an existing rigging-tube run
• Joining two shorter pieces of 2" rigging hose
• Repairing a damaged section without replacing the entire tube
• Adapting an existing installation after an engine or transom change
• Rerouting or reorganizing an outboard rigging bundle

Why Use a Rigging Tube Union?

A union can make a rigging repair or modification easier when the existing tube is otherwise still in good condition.

Instead of replacing the full length of hose, the installer can use a compatible union to connect a new section where additional length or a repair is needed.

This can be especially helpful during engine repowers, steering-system changes or transom rerigging projects.

Choosing the Right Rigging Protection

Installation Tips

• Confirm both sections of rigging hose are compatible 2" tube.
• Cut damaged tube back to a clean section before joining if needed.
• Position the union where the rigging can still flex naturally.
• Do not place the union directly at a severe bend.
• Leave enough slack for full steering movement.
• Verify trim and tilt movement before finalizing the installation.
• Do not compress fuel hose, steering hoses or control cables inside the tube.
• Inspect the entire rigging bundle for chafe while the tube is open.

When is a Rigging Hose Union Useful?

A union is particularly useful when the existing rigging tube is still serviceable but is no longer long enough for the installation.

Examples include:

• Installing a replacement engine with a different rigging location
• Adding length after changing the transom setup
• Repairing one damaged section of tube
• Changing steering or rigging geometry
• Extending existing 2" rigging hose rather than replacing it completely
