Product Description
QST-4 QST-4-100 QST-6 QST-6-100 Festo QST Series Push-in T-connector
The Festo QST Series Push-in T-connector is a high-performance pneumatic fitting designed for reliable tube-to-tube connections in industrial automation systems. Adopting the push-pull principle, it enables effortless and quick installation—simply push the tube into the connector until it clicks into place, eliminating the need for complex tools or additional fasteners. With an optional mounting position and a wide operating pressure range of -0.095 MPa to 0.6 MPa (full temperature range), this T-connector ensures stable performance in various pneumatic setups, effectively distributing compressed air or water to multiple directions while maintaining airtightness.
