Technical Description: Our 21 series is a larger version of the 20 series. This single hand operated, quick connect coupling is ideal wherever space plays a major role. It can be supplied as straight through (no valve), single shut-off or double shut-off. This series is available in thermoplastics as well as RectuKey versions.
Applications: Laboratories, gas providing, presentation, learning systems, filling systems, breathing air, chemistry, just to avoid a mix of various mediums.
Advantages: A quality coupling which has the advantages of single hand operation and small size as well as a multitude of connecting options.
Working Pressure: PB = 35 bar, maximum static working pressure with safety factor of 4 to 1.
Working Temperature:* -20°C up to +100°C (Buna N) depending on the medium.
