Orion Motor Tech 2.5L Pressure Brake Bleeder Kit — 50.7mm Adapter, Single-Operator Hand Pump

The Orion Motor Tech OMT 2.5L Pressure Brake Bleeder Kit with 50.7mm adapter is a single-person system that pressurizes fresh brake fluid into the lines and captures old fluid for faster, cleaner brake bleeding.

When you need to replace contaminated brake fluid or remove air from hydraulic lines, a dedicated pressure bleeder speeds the job and avoids the back-and-forth of pump-and-pedal methods. This Orion Motor Tech kit combines a 2.5-liter pressurizable reservoir, a 500 mL collection bottle, and a 50.7 mm (2") adapter that fits many Japanese and Korean models plus several Fords, so you can perform a complete brake service at the shop or in your garage without a helper.

How does the pressurizable reservoir simplify brake bleeding?

Pressurizing the reservoir forces new fluid through the master cylinder and out the caliper or wheel cylinder bleed screws, flushing air and contaminants in one continuous flow. That uniform pressure eliminates the need for a second person to pump the brake pedal and reduces the risk of introducing more air.

• 2.5 L polyethylene reservoir holds enough fluid for a full-system flush.
• Hand pump creates steady pressure for single-operator use.
• Transparent material lets you monitor fluid level and color.
• Pressure relief valve ensures safe operation during service.

Will the 50.7mm adapter work on my vehicle?

The included 50.7 mm (2") adapter is designed to seal many master cylinders used by manufacturers such as Ford, Nissan, Infiniti, Mitsubishi, Subaru, Kia, and Hyundai. It’s supplied to give a secure fit for common applications, but confirm compatibility with your specific master cylinder opening before use.

• 50.7 mm adapter fits many North American, Japanese, and Korean models.
• Works with common master cylinder mouth sizes—check vehicle manual for exact fit.
• Rubber sealing surface conforms to irregular edges for leak-free pressurizing.
• Adapters can be swapped if your vehicle uses a different master cylinder diameter.

What components are included and how durable are they?

The kit ships with a 2.5 L polyethylene pressure bottle, a 500 mL bleed collection bottle, silicone hoses, the 50.7 mm adapter, and a manual hand pump. Materials are chosen for chemical resistance and heat tolerance to stand up to brake fluid and workshop conditions.

• Polyethylene reservoir resists chemical corrosion and cracking.
• Silicone tubing endures heat and remains flexible during use.
• 500 mL collection bottle keeps expelled fluid contained and visible.
• Hand pump and fittings built for repeated home or professional use.

How do I use this kit safely and effectively?

Fill the reservoir with the correct DOT-spec brake fluid, attach the proper adapter to the master cylinder, pressurize the system with the hand pump, then open wheel bleeders one at a time while directing expelled fluid into the collector. Work methodically from the wheel furthest from the master cylinder toward the closest to ensure air-free fluid throughout the system.

• Always use the vehicle manufacturer’s specified brake fluid type.
• Start bleeding on the farthest wheel, then proceed closer to the master cylinder.
• Monitor reservoir level to avoid drawing air into the fresh fluid supply.
• Depressurize and inspect seals before storage to prolong kit life.

Who is this for: The Orion Motor Tech OMT 2.5L Pressure Brake Bleeder Kit is aimed at DIY mechanics, independent shops, and fleet technicians who want a safer, faster way to flush brake systems without an assistant. It’s particularly useful for owners of compatible Ford, Nissan, Infiniti, Mitsubishi, Subaru, Kia, and Hyundai vehicles, or anyone who services multiple cars and values clean collection and chemical-resistant components for repeated use.
