Adapter for Brake Press Gauge to Metric Caliper

The ALLSTAR PERFORMANCE Adapter for Brake Press Gauge to Metric Caliper (ALL 11022) is a precision thread adapter engineered to bridge standard 1/4-28 inch brake pressure gauge fittings with metric 10 mm x 1.50 threaded calipers. This steel adapter, finished in zinc oxide for corrosion resistance, eliminates the need for separate gauge systems when integrating metric brake diagnostic equipment with imperial-threaded pressure sources—a common challenge in mixed-platform brake system testing and verification.

Constructed from durable steel with a zinc oxide protective coating, this adapter maintains structural integrity across repeated pressure cycles and environmental exposure. The 1/4-28 to 10 mm x 1.50 thread conversion accommodates the dimensional mismatch between North American brake pressure gauge standards and metric brake system specifications—a critical detail for technicians and engineers working with European, Asian, and modern domestic metric brake architectures. The compact form factor (4 × 0.95 × 7 inches) ensures accessibility in tight engine bay spaces without requiring complete brake line reconfiguration or expensive system modifications.

This adapter is essential for automotive technicians, brake system engineers, and restoration specialists working with metric brake calipers on vehicles equipped with imperial-standard pressure gauge ports. Common applications include brake pressure diagnostics on import vehicles, brake system bleeding procedures with metric hardware, and pressure verification during caliper replacement or suspension system work. The adapter eliminates guesswork in brake system diagnostics by enabling direct pressure measurement without adapter stacking or improvised solutions that compromise accuracy or system integrity.

ALLSTAR PERFORMANCE has long served the automotive aftermarket and professional service sector with precision fasteners and adapters. This single-unit brake pressure gauge adapter represents the kind of practical, standards-bridging component that makes precision brake diagnostics accessible without full system replacement or specialized equipment duplication.
