Hose fittings with clamp units - Part 7: Cam locking couplings EN 14420-7:2022

Publication date:   Dec 15, 2022

Scope

This document specifies the design, materials, dimensions and marking requirements for cam locking couplings that serve as the link between hoses and connections to transport liquids, solids and gases, except liquid gas and steam.
For all sizes of aluminium cast material couplings and for all couplings of size DN 100, the pressure range is from -0,8 bar to 10 bar in the working temperature range from -20 °C to +65 °C. All other couplings according to this document are capable of operating within the pressure range from 0,8 bar to 16 bar in the working temperature range from -20 °C to +65 °C.
