The 42mm × 35mm End Feed Fitting Reducer is an internal reducer with a 42mm spigot end that pushes inside a 42mm fitting, and a 35mm socket that takes 35mm copper tube. It lets you run 35mm tube into a fitting sized for 42mm. Joined with a soldered capillary joint and suitable for hot and cold water and central heating. Manufactured from copper to BS EN 1254-1 and fits copper tube to BS EN 1057.
