If you need a safe way to disconnect pneumatic tools from air supply lines with one hand, use this quick-connect coupling from RS PRO. It features a built-in valve that seals off upstream airflow when disconnecting, so it prevents leaks and sudden bursts of air pressure. The compact coupling has a sturdy steel construction for durability and a nickel-plated finish to provide resistance to corrosion. This makes it a tough and long-lasting product that can tolerate frequent, heavy use. This versatile connector is compatible with a wide range of common pneumatic components, including Rectus Series 25 and 26 parts, so it's easy to integrate into an existing system. Its high flow rate of up to 1800 L/min makes it ideal for use with powerful industrial tools such as nail guns and impact drivers.
