Model Identifier QS-G1/2-12
Official Part Number 186104
GTIN Standard 4052568014612

Technical Overview

Straight connector for 12mm OD tubing and G1/2 male thread. Built with nickel-plated brass housing, NBR seals, and handles -0.95 to 14 bar pressure.

Key Features

  • Straight shape design with a reliable push-pull connection principle
  • G1/2 male thread and 12 mm outer diameter tubing connection
  • Broad operating pressure range from -0.95 bar (vacuum) to 14 bar
  • Constructed with a highly durable nickel-plated brass housing
  • Features an NBR tubing seal and a high-alloy stainless steel tubing clamp
  • Standard external hexagon (AF 24 mm) mounting for quick installation
  • Wide operating temperature range from -10 °C to 80 °C

Robust push-pull locking mechanism with nickel-plated brass construction ensures leak-free pneumatic connections up to 14 bar.
