With modern construction techniques and site safety requirements, copper press and push-fit fittings provide fast and efficient jointing techniques that will result in reliable copper installations. Both types of fittings offer flame-free jointing, ideal for the installation of copper building services with fast-track building systems.
For pipework installations that operate at higher temperatures or pressures than can be tolerated by soft capillary soldered fittings, e.g. steam services, or where grease-based fluxes are prohibited e.g. oxygen lines, a range of high-duty fittings is available. High-duty fittings usually contain integral rings of silver brazing alloy, though end-feed types are also available.
Melting points for brazing filler metals can be around 650oC, much higher than the 220 - 240oC typical for solder filler metals.
Compression jointing systems have been continuously developed and improved for over fifty years to the point where they are, in the hands of the competent, professional installer, utterly reliable.
