Copper endfeed fittings for high operating pressure


FRABO G-SIZE is the copper endfeed fittings series with increased thickness designed and manufactured for welded joints installations subject to high operating pressure or severe mechanical stress. FRABO G-SIZE complies with the requirements of  EN 1254-1 and it is ideal for industrial refrigeration plants; compressed air systems; distribution of technical gases with high pressures. 

FRABO G-SIZE copper solder fittings are explicitly designed for withstanding higher operating pressures and heavier working conditions than those that can be handled by common solder fittings
