Single handed operated, compact, high flow rate versatile Quick Connectors. |

 |
| |
|
The series 21QL is a double shut-off coupling in which both couplings and plugs are fitted with valves. The valves in both the coupling and the plug open when connected. Both valves close virtually simultaneously when disconnected, ensuring minimum leakage loss.
The coupling offers a single handed operation, has extremely compact dimensions and a high flow rate with a multitude of connection options, e.g. with air tools, pneumatic, medical engineering, air supply for respiratory purposes, diving equipment, measuring and control equipment, laboratory installations, chemistry, analysis and dosage engineering.
The series 21QL is a standard quick connect coupling with single-hand operation. The coupling allows high flow-rate and small dimensions. The coupling allows a high flow rate in small design. The series allows numerous connecting possibilities options and is thus versatile, e.g. at air-pressure tools, medical engineering, laboratory installations, chemistry, measuring and control equipment, mechanical engineering etc.
