1850A Pressure Tester & Bleeder Adapter – Cooling System and Brake

The Motive Products 1850A Adapter is a dual-purpose tool that bridges the gap between cooling-system pressure testing and brake bleeding. Use it with the Motive Power Tester to diagnose cooling-system leaks, or connect it to a Motive Power Bleeder tank for pressure brake bleeding — one adapter serving two of the most common hydraulic service tasks in any shop.

Application

• Cooling System Pressure Testing – connects the Motive Radiator Power Tester to coolant reservoir or radiator filler necks for leak detection on import and domestic vehicles
• Brake Bleeder Adapter – mates with Motive Power Bleeder tanks for one-person brake or clutch bleeding where fitment is compatible
• Suitable for a wide range of import and domestic vehicles with compatible reservoir or filler neck geometry

Key Features

• Dual-Purpose Design – works with both Motive pressure-testing and brake-bleeding systems.
• Universal Fitment – adapts to a broad range of reservoir and filler-neck styles on import and domestic vehicles.
• Durable Construction – resists coolant, DOT 3/4 brake fluid, and shop chemicals.
• Quick-Disconnect Compatible – connects to Motive Power Tester and Power Bleeder hoses via stainless quick-disconnect.

How to Use

For cooling system testing: seat the 1850A on the reservoir or filler neck, connect the Motive Power Tester, and pressurize to the cap rating. Monitor for pressure drop. For brake bleeding: connect to a Motive Power Bleeder tank, pump to 15–20 psi, and bleed each circuit. One adapter — two essential shop tasks.
