Orion Motor Tech 2.5L Pressure Brake Bleeder Kit with 50.7mm Adapter, One‑Person Operation

The OMT 2.5L Pressure Brake Bleeder Kit is a single-operator brake-fluid exchange and bleeding system that uses a 50.7mm adapter to fit many 3-tab twist-lock master cylinders.

This compact, workshop-ready kit from Orion Motor Tech streamlines brake maintenance by pressurizing fresh fluid into the master cylinder while collecting old fluid in a separate reservoir. It combines a large 2.5L supply bottle, a 500mL collection bottle, and heat- and chemical-resistant hoses so one technician can purge air and contaminants from the brake lines without a second person.

How does this kit simplify bleeding brakes?

The kit uses positive pressure to force new brake fluid through the system, pushing trapped air and old fluid out into the supplied collection bottle. You operate the integrated hand pump to pressurize the supply bottle, then open each bleeder valve at the wheels to purge lines in turn.

• Hand pump pressurizes reservoir for one-person operation
• Clear collection bottle lets you watch expelled fluid
• Pressure-driven flow reduces bench time and mess
• Adapters and hoses fit common master cylinder designs

Which vehicles will the 50.7mm adapter work with?

The included 50.7mm (2") adapter is designed for many 3-tab twist-lock master cylinder designs. This makes the kit compatible with a wide range of domestic and import models, particularly those from the listed manufacturers.

• Fits many Ford, Chrysler, Dodge and Jeep 3-tab systems
• Compatible with several Nissan, Hyundai and Kia master cylinders
• Works with other vehicles using the same 50.7mm twist-lock format
• Adapter simplifies connection—no special tools required

What materials and capacity details should I expect?

The main reservoir is a 2.5-liter polyethylene bottle and the kit includes a 500mL plastic bleeder collection bottle. Hoses are made from silicone that resists heat, wear, and chemical attack for reliable, reusable service.

• 2.5L supply bottle holds enough fluid for a full system flush
• 500mL clear collection bottle for observing expelled fluid color
• Polyethylene and silicone construction resists brake fluid corrosion
• Components designed for repeated workshop use

How do I use the kit safely and effectively?

Fill the large reservoir with fresh brake fluid, attach the 50.7mm adapter to the master cylinder, pressurize with the hand pump, then open each wheel bleeder until clear fluid emerges. Monitor pressure, avoid over-pressurizing, and dispose of contaminated fluid responsibly.

• Always match DOT fluid type recommended by the vehicle manufacturer
• Keep an eye on the collection bottle to stop when fluid clears
• Release pressure slowly before disconnecting the adapter
• Clean spilled fluid promptly—brake fluid can damage paint

Who is this for? The Orion Motor Tech OMT 2.5L Pressure Brake Bleeder Kit is aimed at DIYers, independent mechanics, and small shops that want a fast, one-person method to flush and bleed brake systems. If you service multiple vehicles or need a compact, durable kit that fits many 3-tab twist-lock master cylinders, this tool delivers the capacity and materials needed for routine brake maintenance without complex setup.
