CTA Tools 7030 Master Cylinder Adapter – 56mm Insert, 79.5mm O.D., Nitto 1/2" Fitting – Compatible with Honda and Acura, Brake Bleeding

The CTA Tools 7030 Master Cylinder Brake Bleeder Adapter is engineered for a precise, leak-free connection to the 56mm master cylinder reservoir design used on many Honda and Acura vehicles. This adapter provides a secure seal that allows technicians to pressure-bleed brake systems quickly, cleanly, and with stable system pressure. Built with exact OEM-matched dimensions, the 7030 features a 56mm internal male insert, a 79.5mm outer diameter, and an 18mm engagement depth to ensure proper seating in brake reservoirs found on Honda Accord, Civic, CR-V, HR-V, Odyssey, Pilot, Ridgeline, and Acura RL, Legend, and NSX models. A professional-grade 1/2" Nitto fitting with 1/8" BSP threads connects directly to most shop pressure bleeder systems, delivering consistent performance during brake service. The 7030 is also included in the CTA 7300M 13-Piece Master Cylinder Adapter Kit, making it a trusted solution in professional repair environments. Because Honda and Acura models use multiple reservoir cap and tank designs—even within the same production years—the 7030 and 7033 adapters are designed for the same applications but differ by 1mm. Measuring the reservoir opening ensures correct selection between 7030 (56mm) and 7033 (55mm). With accurate sizing and durable construction, the CTA 7030 provides long-lasting, reliable performance for repeated brake bleeding operations.
