Inlet Fitting 77 / 78 Series Master Cyl

The Inlet Fitting 77 / 78 Series Master Cyl from TILTON is a precision hydraulic adapter designed for high-performance braking systems that demand reliable fluid routing and leak-free operation. This fitting serves as a critical connection point between brake lines and Tilton's industry-standard 77 and 78 series master cylinders, making it essential for motorsports applications, race cars, and custom brake installations where hydraulic integrity is non-negotiable. Whether you're building a track-focused vehicle or upgrading an existing braking circuit, this inlet fitting ensures proper fluid delivery to your master cylinder inlet port.

Constructed from anodized aluminum, this straight-port adapter converts a 6 AN male connection to a 4 AN male configuration, providing a compact and weight-efficient solution for tight engine bay layouts. The black anodized finish offers both corrosion resistance and a professional appearance while protecting the aluminum substrate in harsh motorsports environments. The straight-port design minimizes turbulence and pressure drop across the fitting, which is critical for maintaining consistent brake response and preventing cavitation within the master cylinder during aggressive braking events.

This inlet fitting is ideal for fabricators, brake system builders, and enthusiasts upgrading to Tilton 77 or 78 series master cylinders in custom applications, race vehicles, or performance street cars. Proper installation requires compatible AN-rated hose and adherence to Tilton's system specifications; ensure line pressure ratings and fluid type match your master cylinder's design parameters. The compact dimensions (2.4 x 0.85 x 2.95 inches) and lightweight construction (0.03 lbs) make it suitable for space-constrained installations without adding unnecessary mass to your braking system.
