Delbraze Brazing Plumbing Fittings

Conex Delbraze fittings are available in sizes 66.7-159mm and are suitable for connection copper tubes in accordance with EN1057 and other standards including ISO 274. Certain configurations are also available for joining 219mm diameter tubes. For sizes below 66.7mm please refer to the section on Conex Delcop End Feed fittings.

Conex Delbraze fittings are designed with a short cup thus economising on filler metals. Most fittings in the range are manufactured from copper or gunmetal thereby being immune to dezincification.

Fittings are designed for brazing applications only and are not suitable to be jointed using the soft soldering technique. Our range of accessories includes brazing rods to EN 1044, brazing flux, mats and an extensive range of flanges.
