Prokomon 3L Manual Brake Bleeder Pump with 4 Adapters — Pressure Gauge & Push‑Button Valve

Prokomon 3L Manual Brake Bleeder Fluid Pump is a single-person, pressurized brake-bleeding system with four master-cylinder adapters for a secure, leak-resistant fit on most cars and light trucks.

Designed to make brake-fluid changes faster, cleaner, and safer, this 3-liter manual pump uses controlled air pressure to push old fluid out of the brake lines into a waste container while you top up the system. The kit combines a clear high-capacity reservoir, a visible pressure gauge, a push-button relief valve on the cap, and four precision adapter caps to fit a wide range of master cylinders—so one technician can complete the job without a second set of hands.

How does the Prokomon pump let one person bleed brakes safely?

The pump pressurizes the reservoir to force brake fluid through the lines while the push-button relief valve lets you stop flow instantly before disconnection. A hanging chain and ergonomic handle free up space and reduce spills during service.

• 3L polyethylene reservoir and waste bottle for extended service intervals
• Visible pressure gauge for monitoring system pressure
• Push-button relief valve to stop fluid flow instantly
• Hanging chain for hands-free operation while working

Which vehicles will the adapter caps fit?

The kit includes four master-cylinder adapters engineered to match common OEM sizes so you can form a tight, leak-resistant seal on many domestic and imported vehicles. Each adapter is labelled by diameter for quick selection during service.

• 43.5 mm cap: Chrysler, Dodge, Jeep, Plymouth applications
• 45 mm cap: Covers many European models
• 49.5 mm cap: Fits Buick, Cadillac, Chevy, Mazda, GMC, and similar
• 50.7 mm cap: For Ford late models, Nissan, Hyundai, Subaru and others

What materials and features improve durability and reduce mess?

All fluid-contact components are molded from high-strength, chemical-resistant polyethylene to withstand brake fluid and repeated pressurization. Upgraded thread and clip designs on the adapter caps reduce the chance of deformation or leaks under pressure.

• Chemical-resistant polyethylene reservoir and waste bottle
• Reinforced fittings and adapters for long-term reliability
• Improved cap structure to minimize leaks when pressurized
• Enhanced clip/thread systems that limit fluid loss during bleeding

How do I control pressure and avoid spills when disconnecting?

The cap houses a push-button relief valve that instantly vents internal pressure before you remove adapters or hoses, preventing spray and overflow. The integrated gauge helps you keep pressure within a safe working range throughout the procedure.

• Internal push-button relief to safely release pressure
• Pressure gauge for continuous monitoring of system pressure
• Secure adapter seals that reduce accidental fluid escape

Who is this for: The Prokomon 3L Manual Brake Bleeder Fluid Pump is aimed at home mechanics, small repair shops, fleet technicians, and anyone who prefers a one-person, tidy brake-fluid change without chasing a second helper. It suits owners of domestic and imported cars, SUVs, and light trucks who need a durable, versatile, and portable bleeding solution that reduces mess and speeds up service.
