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.
