Festo QSL-6 Push-In L-Connector

Model Identifier QSL-6
Official Part Number 153071
GTIN Standard 4052568031640

Technical Overview

The Festo 153071 (model QSL-6) is a high-performance 90-degree push-in L-connector designed for efficient pneumatic air and water routing. Operating on a push-pull principle, it accommodates 6mm outside diameter tubing on both ports. Constructed with a durable polybutylene terephthalate (PBT) housing, NBR tubing seals, and a high-alloy stainless steel tubing clamp, it ensures secure and leak-free connections in dynamic industrial environments. This versatile fitting supports a temperature-dependent operating pressure range of -0.95 bar (vacuum) up to 14 bar, and operates reliably in ambient temperatures from -10°C to 80°C. It is fully RoHS-compliant and suitable for applications requiring CRC Class 1 low corrosion stress resistance.

Key Features

  • Supports compressed air (ISO 8573-1:2010) and liquid water mediums
  • Wide operating pressure range from -0.95 bar (vacuum) to 14 bar
  • Robust PBT housing with a high-alloy stainless steel tubing clamp
  • Standard 6mm O.D. tubing connection on both inlet and outlet ports
  • Broad ambient temperature tolerance spanning -10°C to 80°C
  • High-quality NBR sealing ensures leak-free dynamic operation
