SKCOAUTO Pneumatic CV Boot Installation Tool with CV Boot — 26–34mm Expander, 1/4" BSP Air Fitting

SKCOAUTO Pneumatic CV Joint Boot Installation Tool is an air-powered expander that stretches CV boots quickly and safely over 26–34mm shafts for fast, repeatable installations.

This pneumatic CV boot installer combines a purpose-built expander tool with a matching CV boot to simplify constant-speed joint maintenance. Built from 45# steel and rubber composite parts, the kit is designed for repeated shop use on cars, trucks and ATVs. The tool uses a 1/4-inch BSP air fitting and expands via a fingertip air valve so technicians can fit boots in seconds without complex attachments or lengthy assembly.

How does the expander speed up CV boot replacement?

The pneumatic fingers expand the boot uniformly, eliminating manual prying and long stretches by hand. That consistent expansion slips the boot smoothly over the joint, reducing time and risk of tearing the boot lip.

• Air-driven expander fingers for even, repeatable expansion
• One-handed valve control lets you time the fit precisely
• Fits 26–34mm shaft diameters and 125mm height boots
• Reduces labor time compared with manual stretching

Will this tool work with different vehicles and hoses?

Yes — the expander is versatile enough for many passenger vehicles, light trucks and ATVs, and it also assists with some cooling system hoses and pipe clamps. Its 1/4-inch BSP thread and replaceable air adapter maximize compatibility with common shop fittings.

• Compatible with most 26–34mm shafts used in CV joints
• Useful for cooling hoses and pipe-clamp tasks in the shop
• 1/4-inch BSP thread lets you swap adapters as needed
• Compact 125mm height fits tight working areas

How durable and safe is the SKCOAUTO pneumatic installer?

The main components are 45# steel and rubber composite, selected for corrosion resistance and long service life under frequent use. The design minimizes wear while the instruction to keep operating pressure below 130 psi reduces risk during operation.

• 45# steel body for structural stability and rust resistance
• Rubber composite fingers for firm grip without damaging boots
• Maximum recommended pressure 130 psi for safe operation
• Cap-retaining screws and simple pre-use checks prevent loosening

How easy is it to use right out of the box?

There is no complex assembly required — place the boot over the expander fingers, actuate the air valve to expand, slide the boot into place, then release. The tool’s straightforward interface and replaceable adapter make it practical for both seasoned mechanics and occasional users.

• Ready to use immediately with standard air lines
• One-step expansion and release process for fast installs
• Replaceable air adapter for different shop fittings
• Minimal maintenance: check cap screws and air fittings before use

Who is this for: The SKCOAUTO Pneumatic CV Joint Boot Installation Tool is ideal for independent mechanics, automotive shops, ATV enthusiasts and fleet maintenance teams who perform frequent CV boot replacements or want a reliable, repeatable way to fit boots without damaging the boot bead. It’s also useful for technicians who need a multi-use expander capable of assisting with some hose and clamp tasks.
