Copper Fittings for Co2

Degreased copper fittings specifically for ACR and manufactured to ASME B16.22-2001 which can be used in assemblies subject to the Pressure Equipment Directive.

The burst pressure of each fitting size at 55ºc has been determined and a safety factor of at least 3 has been applied to establish a recommended maximum working pressure.

All testing has been conducted in accordance with BS EN 378-2:2008 (+A1:2009).
