22mm x 12mm Endfeed Fitting Reduced Coupling (Copper) – EFSTC-22E

The EFSTC-22E is a copper Endfeed reduced coupling used to join 22mm and 12mm copper pipework. It’s particularly suited for precise installations where large-to-small diameter transitions are needed, such as radiator branches, control loops, or specialist plumbing designs. When soldered, it provides a permanent, leak-free connection.

• Connects 22mm to 12mm copper tube
• Compact design with internal pipe stop
• Excellent for custom and small-bore system layouts
• Forms a durable soldered joint with minimal flow disruption
