Festo QSL-1/8-6 153047 Push-in L-Fitting R1/8 to 6mm

Festo QSL-1/8-6 is a 90° angled push-in L-fitting (threaded adapter) that connects a male R1/8 (BSPT) thread to 6 mm OD pneumatic tubing. The fitting is 360° orientable after installation, allowing alignment along all axes even after the threaded connection is tightened. The push‑pull principle enables tool‑free assembly and disassembly, and the blue release ring provides visual identification of the release mechanism. The tapered ISO R-thread has a self‑sealing PTFE coating, which allows the fitting to be re‑used multiple times without additional sealing components.
