Quick Change Adpt.

The Longacre Quick Change Adapter (SKU LON52-50240) is a precision-engineered tire pressure relief valve adapter designed for serious track enthusiasts and shop professionals who demand rapid equipment changeover. This set of four aluminum adapters bridges the gap between Longacre tire pressure relief valves and quick-change coupling systems, eliminating fumbling with threads during critical pit stops or tire pressure adjustments. Built for high-performance applications where every second counts, this adapter integrates seamlessly into professional tire management workflows on race vehicles, test platforms, and diagnostic benches.

Constructed from durable aluminum, the Quick Change Adapter features a 5/8-inch connection interface that maintains full compatibility with standard Longacre tire pressure monitoring systems. The quick-change design eliminates manual valve threading, reducing connection time and minimizing the risk of cross-threading—a common issue during high-pressure pit operations. Each adapter in this four-piece set is precision-machined to ensure consistent, leak-free sealing, critical for maintaining accurate tire pressure data during performance testing or racing conditions. The compact footprint (4.15 x 0.85 x 5.55 inches) and lightweight construction (0.13 lbs per unit) make these adapters ideal for mobile tire carts and trackside equipment stations.

Professional mechanics, race teams, and automotive shops benefit most from this adapter set, particularly those running multi-vehicle test programs or frequent tire specification changes. Installation is straightforward—simply connect the adapter to your Longacre tire pressure relief valve, then engage the quick-change coupling to your inflation system. The set of four accommodates most modern tire pressure management rigs, allowing technicians to maintain multiple vehicle setups without tool changes. Whether you're managing tire pressures for circle track racing, drag racing, autocross, or high-performance street car tuning, the Longacre Quick Change Adapter streamlines workflow and ensures consistent pressure readings across your fleet.
