CMTOOL Master Cylinder Bleeder Kit — 20‑pc Aluminum Adapter Set with Quick Connect for Most Vehicles

CMTOOL Master Cylinder Bleeder Kit is a 20-piece aluminum brake bleeder adapter set with a quick connector designed to fit most vehicles and simplify pressure bleeding and fluid changes.

This comprehensive kit supplies 19 different adapter fittings plus a quick-connect coupler, all housed in a molded carrying case. The adapters are machined from corrosion-resistant aluminum with gold-plated finishes and internal rubber seals to deliver reliable sealing on master cylinders and fluid reservoirs. Engraved serial numbers on each adapter speed up selection, and the set works with manual pumps, power bleeder tanks, and many pneumatic or electric bleeding tools.

Which vehicles and reservoirs will these adapters fit?

The kit covers a broad range of domestic and import cars, SUVs, and light trucks by offering many common thread sizes and sealing profiles. One adapter can be modified or paired with your existing pump, making it flexible for older and newer vehicles alike.

• Includes adapters compatible with Benz, BMW, Audi, Tesla, Lexus and many other makes
• 19 distinct adapters to match most master cylinder and reservoir openings
• One quick-connect coupler for fast hose attachment to pumps and bleeder bottles

How does the kit ensure leak-free pressure bleeding?

Each adapter is fitted with an internal rubber sealing ring that conforms to reservoir lips and prevents fluid loss during pressurization. The aluminum bodies are gold-plated to resist corrosion and keep mating surfaces smooth for reliable pressure hold.

• Rubber O-rings inside adapters provide positive sealing under pressure
• Gold-plated aluminum resists rust and maintains consistent threads
• Engraved numbers let you match adapter to vehicle quickly and accurately

What tools and procedures is this set compatible with?

The CMTOOL kit works with both manual and powered systems: power bleeder tanks, hand pumps, pneumatic bleeders, or electric fluid exchange units. The included quick connector lets you snap a standard hose in place, so switching between tools is fast.

• Works with power bleeder tanks and manual pump setups
• Quick-connect coupler for fast hose-to-adapter attachment
• Compatible with most electric and pneumatic brake bleeding/exchange machines

How is the kit stored and organized for workshop use?

All pieces come in a custom-molded plastic carrying case that secures each adapter to prevent damage in transport and keeps fittings identifiable. The engraved numbering and compact layout make storage, inventory, and job-site portability straightforward.

• Custom plastic carrying case for secure storage and transport
• Clearly engraved adapter numbers matching the included reference manual
• Compact footprint fits into a toolbox or shop cart without rattle
