Festo QSL-1/8-8 L-Fitting R1/8 to 8mm

Technical Overview

The Festo QSL-1/8-8 (Part Number 153048) is a highly reliable L-shaped push-in pneumatic fitting designed for efficient compressed air and vacuum system integrations. Engineered with a durable PBT housing, it provides a 360-degree orientable R1/8 threaded connection and a reliable push-pull mechanism accommodating 8 mm outside diameter tubing. The fitting ensures leak-free fluid transmission over a broad ambient temperature range of -10 °C to 80 °C and supports dynamic system pressures from -0.95 bar (vacuum) up to a maximum of 14 bar. High-alloy stainless steel tubing clamp components guarantee secure hose retention under vibration, while the premium NBR seal allows compatible usage with compressed air according to ISO 8573-1:2010 standards.
