Teodute pneumatic CV boot installation tool — 115mm capacity, air-powered expander with spare O-rings

This compact, workshop-ready tool uses a controlled air-driven expansion mechanism and replaceable expander fingers to stretch and position boots cleanly and consistently. Built from durable 45# steel and rubber components, the kit is corrosion-resistant and supplied with accessories so technicians and DIYers can complete installations and clamp fittings without improvising. It fits many passenger cars, light trucks, UTVs and ATVs, and also doubles for installing cooling system hoses and similar hose-clip applications.

How does the tool speed up boot installation?

The pneumatic actuator expands the expander fingers instantly at the push of a button, eliminating repeated manual stretching and prying. That controlled expansion reduces installation time and helps protect the boot from pinches or uneven stretches.

• Installs boots up to 115mm diameter without axle removal
• One-button expansion and release for fast cycles
• Consistent spread avoids boot damage and rework
• Includes spare O-rings and fittings for extended use

What vehicles and parts is the Teodute expander compatible with?

The expander is designed with shaped, galvanized claws and an adjustable spread so it works with a wide range of CV and steering boots across many makes. Its universal design also makes it useful for fitting large rubber hoses and securing hose clamps in cooling or intake systems.

• Compatible with many passenger cars, light trucks, UTVs and ATVs
• Works on rubber CV boots and steering boots up to 115mm
• Also suitable for cooling system hoses and clamp installations
• Galvanized claws for broad brand compatibility (Citroen, Fiat, GM, Mercedes, etc.)

What safety and maintenance steps should you follow?

Operate the tool with regulated air pressure and routine checks to keep performance reliable and safe. Use PTFE tape on air fittings, keep operating pressure below the recommended limit, and inspect cap screws and O-rings before each use.

• Apply PTFE tape to hose nipples to prevent air leaks
• Keep operating pressure under 116 psi to protect components
• Check the cap-retaining screw and O-ring condition before use
• Replace worn fingers or O-rings from the included spares
