Also, ideal for use on idle or storage trailers – preventing the trailer and its contents from being moved away . Available in visible red plastic with built in Brass Key Lock Cylinder.

• Carefully Selected Materials: The heavy-duty truck handgrip valve air source lock is made of PA+ABS engineering plastic, wear-resistant and impact-resistant, suitable for harsh environments such as outdoors and docks.
• Universal Design: Compatible with most handgrip valve air source interfaces on the market, while also accommodating European and American standards, eliminating the need for separate adaptations for different vehicle models/container types.
• Lightweight and Compact Design: Easy to carry and install, suitable for narrow interface spaces.
• Through a precise sealing design with rubber parts aligned with the air holes, the air source interface is effectively sealed and isolated after locking, preventing air source leakage during downtime and ensuring the safety of energy isolation.
• Dustproof design effectively resists dust intrusion at docks/during transportation, extending the service life of truck handshake valves.
• Integrated lock cylinder design with a unique, non-copyable key, ensuring locking security.
• High-visibility red warning for easy identification during on-site security inspections

Suitable for logistics companies, dock storage enterprises, container operators, etc.

• Use the provided key to open the lock, disassembling it into two parts: A (with lock cylinder) and B (U-shaped component). (Note: To ensure a tight seal, please clean the air supply interface before locking to remove impurities and oil.)
• Insert A (with lock cylinder) into the valve port from one side, ensuring the rubber parts are precisely aligned with the air vent for a secure seal.
