The Festo QSMY-6-4 is a Y-shaped pneumatic adaptor used to split or combine air lines where different tube sizes are required. It connects one 6 mm push-in tube to two 4 mm push-in tubes, making it useful in compact pneumatic systems where space and routing are limited. This fitting is generally utilised in control cabinets, automation equipment, and small air distribution systems where clean, reliable tube connections are required.
The adaptor uses push-in connections on all ports, allowing tubes to be installed or removed quickly without tools. Once inserted, the tubing is held securely, reducing the risk of leaks during normal operating pressure.
The QSMY-6-4 is made from lightweight, durable materials suitable for industrial pneumatic environments. Its compact size is helpful when working in tight panels or machines with limited space. The fitting maintains alignment well, so connected tubes stay in position during operation.
It is often used when a single air supply needs to feed smaller pneumatic components without redesigning the entire tube layout.
