Fitting M/C 11/16-20 -3 AN Compact Remote Resv.

The Wilwood Fitting M/C 11/16-20 -3 AN Compact Remote Resv. adapter is a precision hydraulic fitting engineered for custom brake system installations where space constraints demand compact solutions. This straight-port adapter transitions from the OEM master cylinder 11/16-20 male thread to a 3 AN male O-ring port, making it essential for fabricators, performance builders, and enthusiasts integrating Wilwood's compact remote brake reservoirs into tight engine bays or custom frames. Whether you're building a hot rod, off-road rig, or track car, this fitting bridges the gap between legacy and modern braking architectures without sacrificing reliability.

Manufactured from black anodized aluminum, this fitting delivers corrosion resistance and lightweight durability critical to aggressive driving environments. The O-ring face seal at the 3 AN port eliminates the need for Teflon tape and provides a bubble-tight connection that withstands repeated thermal cycling inherent in high-performance braking. The straight-port design minimizes flow turbulence and pressure drop—important when every millisecond of pedal response counts during competitive driving or emergency stops. Wilwood's compact remote reservoir design pairs perfectly with this adapter, allowing builders to relocate brake fluid storage away from heat sources and improve weight distribution.

This adapter suits custom builders who demand OEM quality without factory constraints, from vintage restoration purists to full-tube-frame racers. Its lightweight profile (0.04 lbs) contributes negligibly to overall system weight while its compact dimensions (2.8 x 0.95 x 4.05 inches) nestle into confined spaces where off-the-shelf solutions won't fit. Installation requires only hand tools and basic plumbing knowledge; ensure the mating 11/16-20 female port is clean and dry, apply a light anti-seize to the threads, and torque to Wilwood specifications for your brake system pressure rating. Pair this fitting with Wilwood master cylinders and proportioning valves for a fully integrated, reliable braking solution.
