GBD 3-3/4" (95mm) Brake Cylinder Flex-Hone 400SC Grit - Brush Research

The Brush Research GBD 3-3/4" (95mm) Brake Cylinder Flex-Hone with 400SC Grit (Model GBD334400) is a professional-grade solution for achieving precise surface finishes in automotive and industrial cylinder applications. Engineered for durability and consistent performance, this heavy-duty Flex-Hone ensures optimal surface conditioning of critical components, promoting proper seal seating and extending part life. It effectively removes peaks and imperfections from cylinder walls, producing an oil-holding crosshatch pattern and a true plateau finish free of cut, torn, and folded metal.

Key Features

• Professional-Grade Construction: Features a robust twisted-in-wire design for consistent performance and longevity.
• Optimal Bore Sizing: Specifically sized at 3-3/4" (95mm) for precise application in brake cylinders and other bores within the 3" to 4-1/2" diameter range.
• 400SC Grit Abrasive: Utilizes 400SC (Silicon Carbide) abrasive globules for effective material removal and superior surface preparation.
• Heavy-Duty Design: Part of the GBD series, known for a longer abrasive length than standard hones, making it suitable for high-production and demanding industrial tasks.
• Self-Centering and Self-Aligning: The tool's unique construction allows it to be self-centering, self-aligning to the bore, and self-compensating for wear, simplifying operation and reducing setup time.
• Enhanced Surface Finish: Creates a consistent cross-hatch pattern and plateau finish crucial for improved oil retention, reduced seepage in hydraulic and pneumatic applications, and extended seal performance.

Applications

• Brake Cylinder Reconditioning: Ideal for re-finishing brake and wheel cylinders in automotive and heavy-duty vehicles.
• Engine Cylinders and Liners: Commonly used for finishing and deglazing block cylinders or liners in stationary diesel engines.
• Industrial Pipe Applications: Suitable for preparing oil and gas pipes for critical sealing requirements.
• Marine Engine Maintenance: Employed in marine engine rebuilding and maintenance for optimal cylinder surface finishing.
• General Industrial Bore Finishing: Applicable to any cylinder or bore requiring deburring or precise surface refinement within its diameter range.
