PM/31 Tire Repair SS17-501 Ball Foot Air Chuck Closed Flow 1/4" FNPT

The PM/31 Tire Repair SS17-501 Ball Foot Air Chuck (Closed) is a professional-grade tire inflation chuck designed for use in tire service shops, garages, and fleet maintenance operations. This closed-flow chuck ensures that air only flows once the inner tang has fully engaged the tire's Schrader valve stem, preventing air loss during connection and disconnection.

Key Features:

• Closed-flow design — air flows only after the chuck engages the valve, minimizing air waste and pressure loss
• Ball foot style — low-profile head seats securely on valve stems for a firm, leak-free connection
• 1/4" FNPT thread — standard female NPT connection for compatibility with most air hoses and inflation equipment
• Durable brass construction for long service life in demanding shop environments
• Compatible with standard Schrader valve stems found on passenger, light truck, and commercial tires
• Sold individually (1 piece per unit)

The SS17-501 is also cross-referenced as 17-501 and is interchangeable with Bowes AC-12501 and other industry-standard ball foot closed air chucks. It is an ideal replacement or spare chuck for professional tire inflators and air service lines.
