Fitting Adapter Tandem M/C 3/16 x 1/2-20

The Wilwood Fitting Adapter Tandem M/C 3/16 x 1/2-20 is a precision-engineered flare nut adapter designed for high-performance brake systems using Wilwood tandem master cylinders. This steel fitting with zinc oxide plating serves as a critical connection point between 3/16-inch hardline tubing and the 1/2-20 inverted flare port on Wilwood master cylinder assemblies. The adapter's compact design and robust construction ensure reliable hydraulic pressure distribution in demanding braking applications where consistency and leak-free performance are non-negotiable.

The inverted flare male configuration creates a sealed connection that resists vibration-induced loosening common in high-performance vehicles and motorsports platforms. Steel construction with zinc oxide corrosion resistance ensures durability in both street and track environments, including exposure to brake fluid and varying moisture conditions. The 1/2-20 thread specification is engineered to mate precisely with Wilwood tandem master cylinder ports, eliminating adapter confusion and ensuring proper torque retention without cross-threading. Compact at just 0.03 lbs, this adapter fits seamlessly within custom brake line routing in tight engine bays or custom brake installations.

This adapter is essential for builders and technicians constructing or repairing custom brake systems, whether for street performance vehicles, track cars, or motorsports applications requiring Wilwood tandem master cylinder integration. It addresses the specific hydraulic interface challenge where 3/16-inch hardline must connect to a larger port specification. Proper fitment of adapters in brake systems prevents leakage, maintains pressure integrity, and protects against catastrophic brake failure—making correct part selection critical for safety-sensitive installations.

Wilwood is recognized in the performance braking industry for precision manufacturing standards. This adapter meets the exacting tolerances required for inverted flare connections, where even minor deviations can compromise seal integrity. The MPN 220-5247 identifier ensures you receive the exact specification for Wilwood tandem master cylinder compatibility—critical when ordering replacement or additional brake system components.
