New Original Festo 153003 QS‑1/4‑6 Push‑in Fitting
1. Product Overview
The part‑number 153003 QS‑1/4‑6 is a genuine Festo straight‑type push‑in pneumatic fitting belonging to the well‑known QS series. It connects a G1/4 external thread port with 6‑mm‑outer‑diameter PU or PA pneumatic tubing. This push‑in‑style connector is designed for compressed‑air pipeline distribution inside automation machinery, machine‑tools, packaging lines and assembly equipment. With high‑quality nickel‑plated brass body and plastic release collar, it realizes quick tube assembly without extra tools. It provides leak‑free connection for compressed‑air circuits and adapts to long‑term cyclic working‑conditions of modern industrial pneumatic systems.
2. Main Functions
- Quick pipeline connection: Firmly fix 6 mm OD pneumatic hoses onto G1/4 threaded ports without screwdrivers or crimping tools.
- Air‑sealing performance: Reliably prevent air leakage under standard working pressure to lower energy‑loss of compressed‑air systems.
- Convenient disassembly: Press down the release collar to pull out tubing rapidly during equipment modification or maintenance.
- Thread‑sealing function: The external thread can be matched with PTFE tape to form tight sealing when installing into valve manifolds and cylinder ports.
- Direction‑stable airflow: Straight‑through internal passage reduces airflow resistance and pressure drop inside the pneumatic circuit.
- Wide‑medium compatibility: Works well with filtered compressed‑air, applicable for both lubricated and non‑lubricated air sources.
- Anti‑loosening property: Nickel‑plated brass body resists vibration‑induced loosening on continuously‑running automated devices.
