Potable integral solder ring fittings- Yorkshire Potable Integral Solder Ring (ISR) capillary fittings in sizes from 6mm to 108mm contain a ring of high quality lead-free solder. When heat is applied, the solder is released into the gap between the tube and the fitting, creating a reliable joint without the need for end-feeding additional solder. Yorkshire Potable general range fittings are manufactured from copper and copper alloy. Available in sizes from 6mm to 67mm, fittings are designed for jointing copper tubes to BS EN 1057 in hot and cold water services, in small bore and minibore central heating, low pressure steam heating, and in vented and unvented closed circuit heating systems. Yorkshire Potable fittings are guaranteed for 25 years against manufacturing defects and are WRAS approved.
Manufactured to BS EN 1254 / BS 864 part 2. Designed for jointing copper tubes to BS EN 1057 (R220, R250 and R290) in a wide range of applications.
