Description

Simplify your heating and boiler system installations with our commercial-grade Endfeed Copper Straight Cylinder Unions. Belonging to the specialized Endfeed/Cylinder Union category, these high-quality fittings are engineered to create a robust, secure, and maintainable connection between standard copper distribution lines and water cylinders, tanks, or boilers featuring a 1" female inlet.

Available in both 22mm x 1"  and 28mm x 1"  configurations, these unions feature a dual-connection design: a precision capillary end for reliable soldering to copper pipework, and a heavy-duty 1" male BSP parallel thread. They provide an essential, high-strength alternative to compression fittings, ensuring long-term system integrity under demanding thermal loads.

Key Features & Plumbing Benefits

  • Dual Size Options: Available in 22mm x 1" or 28mm x 1" variants to match standard primary heating loops and hot water cylinder feeds perfectly.

  • Easy Maintenance & Removability: The union design allows for quick isolation and disconnection of cylinders or plant equipment for servicing or replacement without cutting the permanent pipework.

  • Premium Copper Construction: Manufactured from pure, deoxidised copper and high-grade brass components for exceptional corrosion resistance, thermal efficiency, and lifelong durability.

  • Leak-Proof Capillary Weld: Internal sockets are turned to strict trade tolerances, optimizing capillary action to pull solder in evenly for an airtight, permanent joint.
