Description
xOverview
The CTA Tools 7030 Master Cylinder Adapter is engineered for a precise, leak-free connection to the 56mm reservoir design used on many Honda and Acura vehicles. This adapter makes pressure-bleeding brake systems faster, cleaner, and more predictable, helping you maintain stable system pressure throughout service.
With exact OEM-matched dimensions, the 7030 ensures proper seating in brake reservoirs across a wide range of models, including Honda Accord, Civic, CR-V, HR-V, Odyssey, Pilot, Ridgeline, and Acura RL, Legend, and NSX. Coupled with a professional 1/2 inch Nitto fitting, it connects directly to most shop pressure bleeder systems for consistent performance.
Key dimensions and connection
The 7030 features a 56mm internal male insert, a 79.5mm outer diameter, and an 18mm engagement depth for accurate seating in compatible reservoir openings. A 1/2 inch Nitto quick-connect with 1/8 inch BSP threads provides fast, secure attachment to bleeding equipment.
Compatibility and fitment notes
Honda and Acura models use multiple reservoir cap styles—even within the same year. See your reservoir opening to confirm the correct adapter: 7030 for 56mm or 7033 for 55mm. This prevents mismatches during service.
What you get and reliability
Durable construction and shop-grade reliability pair with the 7030's secure seal to maintain stable pressure during bleeding on compatible systems. The 7030 is also included in the CTA 7300M 13-Piece Master Cylinder Adapter Kit, making it a common choice in professional repair environments.
Usage tips
- Measure reservoir opening before ordering to ensure correct fit (56mm vs 55mm).
- Use the 1/2 inch Nitto connection with a compatible bleeder system for a leak-free setup.
Practical benefits
- Precise seating reduces the chance of leaks during bleed cycles.
- Direct compatibility with Honda/Acura reservoirs supports efficient service across multiple models.
- Robust, shop-grade build is designed for repeated professional use.
