PM/31 Tire Repair 17-504FC Euro-Style Clip-On Closed Air Chuck 1/4" NPT

The PM/31 Tire Repair (Xtra Seal) 17-504FC is a Euro-style clip-on closed air chuck designed for use on live air lines in professional tire service environments. Featuring a 1/4" NPT female threaded inlet and a 3/4" hex body, this chuck connects securely to standard tire valve stems for fast, reliable inflation and pressure checks.

The closed-flow design makes this chuck ideal for direct connection to pressurized air lines — air only flows when the chuck is properly engaged on the valve stem, minimizing air loss during use. The Euro-style clip-on mechanism provides a quick, positive lock onto the valve for hands-free inflation.

Key Features:

• Euro-style clip-on design for secure, hands-free valve stem engagement
• Closed-flow valve — air flows only when properly seated on the valve stem
• 1/4" NPT female thread for standard air line and inflator gauge connections
• 3/4" hex body for easy installation and removal with standard wrenches
• Rated for use up to 150 PSI maximum operating pressure
• Compatible with standard bore Schrader-type tire valve stems
• Manufactured by 31 Incorporated (Xtra Seal), a leading supplier of professional tire repair tools and accessories
