Engineered to withstand rigorous commercial environments, the 753S-12 provides a permanent, leak-proof extension from the base valve. Its unique hand-bendable design can be easily formed by hand to clear any wheel obstacle or configuration without kinking the internal airway.

Key Features & Benefits

• Leak-Proof Engineering: Features a specialized Teflon gasket at the base and a 3/4" heavy-duty hex sealing nut. The internal lead seal bites deeply into the thread to completely eliminate vibration-induced air leaks.
• Flexible Adaptation: Can be repeatedly shaped by hand to match tight or complex wheel profiles.
• Complete Mounting Hardware: Includes two heavy-duty lock nuts to securely anchor the extension to a rim bracket, ensuring stability under highway speeds or harsh vibrations.
• Universal Core Compatibility: Relies on the vehicle's existing original large-bore valve core and cap, ensuring uncompromised airflow performance.
