Pneumatic CV Boot Expander Gun, 20-110mm Capacity

Brief Overview

The CV BOOTGUN is a pneumatic-powered expander designed specifically for stretching flexible CV boots onto drive shafts without causing damage. This tool delivers controlled, even pressure through six curved metal expansion fingers, eliminating the risk of pinching, tearing, or misalignment during installation. Powered by compressed air at 4-7 bar, it transforms a task that typically requires significant manual force and skill into a repeatable, damage-free operation. For shops handling regular CV joint replacements, this tool pairs effectively with manual CV boot installation pliers to provide both mechanical and pneumatic installation options.

Key Features

• Controlled Pneumatic Expansion: Six curved metal fingers spread evenly to 110mm maximum diameter, distributing pressure uniformly across the boot perimeter
• Safe Operating Range: 20-110mm capacity covers the majority of front-wheel-drive CV applications
• Low Air Pressure Operation: 4-7 bar requirement means compatibility with most shop compressors without excessive energy consumption
• Metal Expansion Fingers: Flat, curved tines with secure fastening prevent accidental separation during operation
• Precision Control: Brass control valve allows technician to meter air pressure for gentle stretching and safe boot engagement
• Durable Construction: Black molded housing with ribbed grip handle and metal quick-connect fitting for reliable daily use
• Lightweight Design: At 2.4 kg, the tool reduces operator fatigue during repetitive installations

Why Resellers Profit from This Tool

• High-Margin Add-On: CV boot replacement jobs are common; offering a pneumatic solution differentiates your shop and justifies premium labor rates
• Speed Advantage: Cuts boot installation time by 40-60% compared to manual stretching, improving shop throughput
• Damage Prevention: Eliminates customer returns from improperly installed boots, protecting your shop's reputation and labor warranty costs
• Repeatable Reliability: Every installation is consistent, reducing rework and the associated labor expense
• Low Operational Cost: Minimal air consumption (4-7 bar) means negligible added expense per job
• Bulk Opportunity: Shops handling fleet maintenance or high-volume service contracts see immediate ROI
