Festo Pneumatic Fitting, 4mm Push-in Tube, Male M5 Thread, Brass, Nickel Plated, Compact RoHS Connector QSM-M5-4

Festo QSM-M5-4 Pneumatic Fitting is a compact, high-precision connector engineered for industrial pneumatic assemblies requiring secure, leak-free tubing attachment. Designed with a 4mm push-in tube connection and a male M5 thread conforming to G standard, this fitting delivers versatile compatibility with small-diameter pneumatic ports commonly found in automation, robotics, and machine-tool environments.

The brass construction of the QSM-M5-4 ensures robust resistance to corrosion, mechanical stresses, and deformation, providing long-lasting service even when subjected to elevated ambient and process temperatures. The durable nickel plating further enhances surface protection, minimizing wear from repeated coupling and exposure to chemicals found in industrial operations.

Installation is optimized for speed and efficiency. The push-in tube coupling supports rapid insertion and release without tools, reducing assembly and maintenance time compared to traditional threaded tube adaptors. This makes it an ideal choice for projects requiring frequent reconfiguration or quick setup in prototyping and bench testing scenarios.

Rated for continuous operation up to 80°C, Festo's connector is suitable for demanding environments such as control manifolds, auxiliary air supply connections, pneumatic tubing routing in electrical cabinets, and compact valve arrays. The RoHS compliance ensures that this fitting meets global standards for restricted-substance content in high-technology assemblies.

The M5 male thread and G standard provide reliable threaded coupling to small pneumatic ports, ensuring compatibility with miniature actuators, valves, or manifolds, and allowing for compact system designs. Its food-grade and chemical resistance are not specified, but for industrial fluid power applications, resistance to moderate chemical exposure is supported by the brass and nickel finish.

Integrate the Festo QSM-M5-4 fitting into automation systems, laboratory instrumentation setups, HVAC equipment, manufacturing control panels, or water treatment platforms where precision air supply routing, easy maintenance, and compliance are required. Its robust design supports high-frequency cycling and reassembly, making it a preferred choice for OEMs, maintenance professionals, and systems integrators.
