Festo QSY-6 – Push-In Y-Connector for 6 mm Tubing

The Festo QSY-6 is a push-in Y-connector that splits one 6 mm tubing line into two. Tubing pushes in by hand and releases with the blue ring, so no tools are needed. It operates at up to 6 bar across its full temperature range (up to 14 bar at reduced temperatures) with compressed air or water, from -10°C to 80°C. The PBT housing, stainless steel clamp, and ISO Class 4 cleanroom suitability make it a good fit for branching air lines to two actuators in industrial pneumatics and automation.
