QSL-1/4-8 Push-in L-Connector (153049) – 1/4" Thread to 8mm Tube 90° Elbow Fitting Festo
The Festo QSL-1/4-8 (Part Number: 153049) is a premium, industrial-grade pneumatic elbow fitting designed for maximum system reliability in tight configurations. As a foundational component of Festo’s trusted Quick Star (QS) series, this 90° L-connector features a highly convenient push-in design that enables rapid, tool-free pneumatic tube connections.
Engineered with a 360° orientable body, it allows the 8mm tube connection to be effortlessly rotated in any direction during installation, simplifying complex hose routing and avoiding kinking. The fitting leverages a robust nickel-plated brass thread paired with a high-alloy stainless steel retaining claw inside, ensuring an absolute airtight seal and structural durability under high operational pressure. The integrated nitrile rubber (NBR) seal guarantees leak-free performance, while the ergonomic blue release ring allows for fast disconnection without damaging pneumatic tubing.
