PCL 1/4" ProConnect Lockon Air Chuck w/ Release Button Open

The CH2A01 Open-End Single Clip-On Connector replaced the CO2 connector, featuring a fully redesigned, high-quality construction for reliable and efficient tire inflation.

As an open-end connector, it allows continuous airflow while clipped onto the tire valve, making it ideal for use with standard single-hose inflators and general tire servicing.

Manufactured from premium zinc alloy, aluminium, and brass, the CH2 offers a non-scratch finish, a vice-like grip for secure, leak-free sealing, and a 360° swivel motion to improve access to hard-to-reach valves. A thumb quick-release ensures fast and safe disconnection, saving time in busy workshops.
