New Original FESTO 177723 CQH‑22‑QS‑16 Pneumatic Reducing Push‑in Connector
Product Overview
FESTO CQH‑22‑QS‑16, part‑number 177723, is a straight reducing push‑in sleeve from the CQH series. It serves as an adapter between the large‑size CQ push‑in system for 22 mm outer‑diameter tubing and the standard QS push‑in system for 16 mm outer‑diameter tubingFesto. Built with POM housing and stainless‑steel retaining claws, this fitting enables transition between different tube diameters without threaded connections. It is widely used in factory automation production lines, packaging machinery, large‑bore compressed‑air ring‑main piping and equipment cabinet pneumatic layouts. It supports both compressed‑air and vacuum circuits for connecting high‑flow main pipelines to smaller‑diameter branch pipelines.
Main Functions
- Diameter reduction transition: Connects 22 mm OD CQ‑series large‑bore tubing to 16 mm OD QS‑series standard tubing.
- Push‑pull quick‑connect principle: Tubing inserts directly; press release ring for disassembly, no special tools required.
- Straight‑through fluid passage: Optimized internal flow channel reduces flow resistance during cross‑size pipeline transition.
- Reliable tube retention: High‑alloy stainless‑steel clamping claws lock tubing securely against pressure‑induced disconnection.
- Vacuum‑compatible performance: Maintains sealing stability under negative‑pressure vacuum conditions.
- Flexible installation: Supports any mounting orientation for machine‑body or cabinet‑internal piping arrangement.
- System‑bridge function: Interconnects Festo CQ large‑flow push‑in fittings and conventional QS push‑in fitting systems.
- Passive connection component, no moving parts for long‑term stable operation.
Technical Characteristics
- Housing and release‑ring material: POM polyoxymethylene; tube‑gripping claw: high‑alloy stainless steelFesto.
- Connection port 1: CQ push‑in interface for 22 mm outer‑diameter tubing; port 2: QS push‑in interface for 16 mm outer‑diameter tubingFesto.
- Nominal internal bore: 11 mm.
- Operating pressure: ‑0.95 bar ~ 7 bar across full temperature range; max ‑0.95 bar ~15 bar under partial temperature conditionsIBF.
- Ambient working temperature: ‑25 ℃ ~ +70 ℃.
- RoHS compliant, meets VDMA 24364‑B1/B2‑L LABS‑PWIS zone III requirements for paint‑industry automation; corrosion resistance class CRC 2Festo.
- Operating medium: Filtered compressed‑air conforming to ISO 8573‑1:2010 [7:-:-]; lubricated compressed‑air is allowed if consistent lubrication is maintained.
