Festo QSL-1/4-6 90° Push-In Pneumatic Fitting

Model Identifier QSL-1/4-6
Official Part Number 153047
GTIN Standard 4052568011055

Technical Overview

The Festo 153047 (Model QSL-1/4-6) is an industrial-grade, 90-degree pneumatic push-in L-fitting designed for efficient and reliable compressed air distribution. Featuring an R1/4 male threaded connection with a PTFE pre-coating for instant sealing, and a 6 mm push-in port for standardized pneumatic tubing, this fitting enables fast, tool-free assembly. The housing is constructed from rugged Polybutylene Terephthalate (PBT) and includes an NBR seal, ensuring leak-free performance across a broad operating pressure range of -0.95 to 14 bar. Furthermore, the fitting is 360-degree orientable, providing exceptional flexibility for routing airlines in space-constrained industrial automation systems, robotics, and complex pneumatic manifolds. Designed to operate safely in ambient temperatures ranging from -10°C to 80°C, the QSL-1/4-6 delivers durable, high-cycle performance in dynamic pneumatic applications.
