Copper solder ring straight couplings come in sizes up to 8mm - 67mm, these couplings are manufactured to BS EN 1254-1:1998 by MasterFlow. All of our solder ring fittings come with lead-free solder to ISO 9453 embedded within them, they’re also WRAS approved and 16 bar pressure rated at up to 30°C with an operating temperature range of 0°C – 110°C.
Solder ring fittings are quick and easy to install, just heat the ends with a blowtorch, the embedded solder will melt creating a watertight joint. These copper pipe fittings are ideal for potable (drinking) water as well as heating and chilled water in conjunction with BS EN 1057 copper pipe and tube.
