Plug quick coupling CEJN NON DRIP (Leak-free) with valve, intended for conveying liquids (water, oil, chemicals etc.). flat surfaces contact minimize any leakage liquids and prevents inclusion air enabling simultaneously easy maintaining quick coupling in purity. socket and plugs in versions with a shut-off valve or without, with the possibility ich alternating connecting allow on achieving three configuration quick coupling: of a free bore, single shut-off (socket must have valve) and double shut-off (Leak-free). available are caps protecting quick coupling against contaminants, when is ono disconnected. in order to ensuring additional safety, when unacceptable is exchange in connection socket-plug possible is coding quick coupling color: green (standard) and optionally black, blue, red, white and yellow or tzw. coding a wrench, where socket and plug have additional grooves and lugs, enabling only properly matched connections quick coupling. Material: brass nickel-plated. sealing: NBR, Viton, EPDM. Working pressure: 20 bar. Operating temperature: od -15°C up to +205°C, depending on kinds seal.
