Copper End Feed Tee Fitting — Equal & Reducing T-Type, ID 6.35mm–67mm

Match the inside diameter (ID) of the fitting to the outside diameter (OD) of your copper pipe. For example, a 6.35mm (1/4") ID fitting is designed for 1/4" OD copper tube. For reducing tees, the format is Inlet x Branch x Outlet — e.g., 22 x 28.6 x 22 means the two run ends are 22mm and the branch is 28.6mm (≈1-1/8"). Always verify your pipe OD before ordering.

Wall thickness typically ranges from 0.8mm to 2.0mm depending on the fitting size. Thicker walls (1.5mm–2.0mm) are generally recommended for larger diameters and higher-pressure applications such as heating systems. For standard domestic cold/hot water lines, 1.0mm wall thickness is typically sufficient. Check the variant options for the wall thickness available for your chosen size.

Copper is naturally corrosion-resistant and is generally suitable for outdoor and underground installations when properly soldered and, where required, wrapped with protective tape or sleeving. In most cases, copper end feed fittings perform well in buried domestic water supply lines. Check local building codes for any additional requirements.

When correctly soldered, copper end feed fittings typically withstand working pressures suitable for standard domestic plumbing and heating systems — generally up to 10 bar for water and heating applications. Actual ratings depend on pipe size, wall thickness, and installation quality. Contact us to confirm for specific pressure requirements.

Yes. These end feed tee fittings are designed to work with standard copper tube conforming to EN 1057 (R220/R250) dimensions, which are widely used in the US, UK, and European plumbing markets. Always confirm your tube OD matches the fitting ID listed in the variant options before purchasing.

Copper fittings are generally approved for use with natural gas and LPG in many jurisdictions when installed by a qualified professional and in compliance with local codes. Always verify local regulations and have gas installations inspected by a licensed plumber or gas engineer. Do not use for gas without professional confirmation.

For potable water systems, use lead-free solder (e.g., 95/5 tin-antimony or silver-bearing solder) with a water-soluble flux. For heating and non-potable systems, standard tin-lead solder may be used where permitted by local codes. Clean the pipe end and fitting socket thoroughly before fluxing and soldering for best results.
