Clamp type coupling assemblies for LPG transfer hoses
This document details a range of hose fittings which may be used with rubber/plastic hoses for the transfer of liquid natural gas LPG (liquid or vapour phase) and natural gas.
The maximum working pressure is 25 bar and the maximum working temperature is 70 °C.
The nominal size for hose fittings with internal and external threads is from DN 15 to DN 75 and for hose fittings with flanges DN 15 to DN 200.
