Features
Precision-machined from brass billets using CNC lathes, each extension features a 0.275" straight bore channel that minimizes airflow restriction during inflation, achieving 22% faster air transfer versus angled adapters. The electroless nickel plating creates a 12μm-thick barrier against galvanic corrosion and UV degradation. Internally, the M7x0.75mm threads are cut to Class 2G tolerance for smooth engagement with Schrader valves, while external knurling (40 TPI diamond pattern) provides 360° grip traction. Pressure-sealed through hydrostatic testing at 2x recommended PSI (150 PSI sustained), the extensions maintain airtight integrity across -40°F to 250°F operational range. The unified 50mm length positions air chucks clear of wheel rims for unobstructed gauge access
