CMTOOL Master Cylinder Bleeder Kit — 20pc Aluminium Adapters with Quick Connector, Gold-Plated Corrosion-Resistant Set

CMTOOL's Master Cylinder Bleeder Kit is a 20-piece aluminum adapter set with a quick connector designed to seal, pressurize and simplify brake and clutch fluid bleeding on most vehicles.

If you perform your own brake maintenance or run a shop, a flexible master cylinder bleeder set saves time and prevents spills. This CMTOOL kit bundles 19 labelled adapters plus a quick-connect fitting in a fitted plastic case so you can match the correct sealing adapter to the reservoir or master cylinder opening, attach a hand or powered bleeder, and move through all fluid ports without makeshift fittings or repeated mess.

How does this kit make bleeding brakes faster and cleaner?

The set gives you a properly sized adapter for nearly every common master cylinder and reservoir shape, so you can achieve a reliable seal and use pressure to push fluid through without repeated topping-off. A quick connector lets you attach a bleeder hose instantly and maintain a steady flow.

• 19 numbered aluminum adapters fit many manufacturers and reservoir sizes.
• Gold-plated, corrosion-resistant finish prevents seizing and leaks.
• Internal rubber seals ensure airtight connections and reduce fluid loss.
• Quick connector attaches to standard bleeder hoses for pressurized bleeding.

Which vehicles and bleeders are compatible with the CMTOOL set?

The kit covers a wide range of applications: passenger cars, SUVs and many light trucks from brands such as Benz, BMW, Audi, Lexus and others, plus many electric vehicles that share common reservoir sizes. It also works with manual, pneumatic and electric pressure bleeders.

• Adapters include sizes to match European, Asian and American master cylinders.
• Works with power bleeder tanks, hand pumps and shop pneumatic systems.
• One adapter can be modified to mate with uncommon or aftermarket pumps.

What materials and features improve durability and sealing?

CMTOOL manufactures the adapters from aluminum with a protective gold-plated surface to resist corrosion and wear from brake fluid exposure. Each adapter includes a rubber O-ring or gasket inside to provide a tight, leak-resistant seal so you can pressurize the system without losing fluid or introducing air.

• Lightweight, high-strength aluminum body resists deformation under pressure.
• Gold-plated coating deters rust and eases cleanup after use.
• Internal rubber sealing rings prevent drips and maintain pressure.
• Clearly engraved serial numbers speed up adapter identification.

How is the kit stored and what accessories are included?

The components ship in a rugged custom plastic case with molded slots for each part, making inventory fast and preventing damage during transport. The set includes the quick-connect fitting and a printed chart linking engraved adapter numbers to vehicle types and reservoir sizes.

• Custom molded carrying case for organized storage and protection.
• 20-piece set: 19 adapters plus quick connector — upgraded from older 17-piece versions.
• Engraved numbers on each adapter match the supplied reference guide.
• Replacement support available if a piece is missing from your package.

If you regularly service brakes or clutch hydraulics and use pressure-assisted bleeding tools, the CMTOOL Master Cylinder Bleeder Kit reduces setup time, minimizes spills and keeps your workspace cleaner.
