In the high-pressure world of racing hydraulics, a single weak link in your brake lines can end your night—or worse. The Longacre 52-45243 Caliper Fitting is a professional-grade adapter designed to provide a rock-solid, leak-free transition between your calipers and your braided stainless steel brake lines.
Featuring a 1/8" NPT male thread on one end and a #3 AN (3/16") male flare on the other, this straight adapter is the industry standard for connecting aftermarket racing calipers (like those from Wilwood or Strange) to high-performance plumbing.
Key Features
-
AN-Standard Precision: The #3 AN flare is machined to exact tolerances, ensuring a 37-degree metal-to-metal seal that won't leak under the 1000+ PSI spikes found in racing braking zones.
-
High-Strength Steel Construction: Unlike soft brass fittings that can strip or crack under torque, this steel fitting is built to withstand the heat and vibration of a wheel-end environment.
-
Optimal Flow Characteristics: The straight-through design ensures unrestricted hydraulic fluid transfer, providing the firm, consistent pedal feel that professional drivers demand.
-
Corrosion-Resistant Plating: Finished with a protective coating to resist the corrosive effects of racing brake fluid and harsh track-side environments.
-
Universal Racing Fitment: The 1/8" NPT thread is the most common inlet size for high-performance racing calipers, making this a "must-have" spare part for any race trailer.
