End Feed Reducing Tee - Branch - 22Mm X 22Mm X15Mm

End Feed Reducing Tee - Branch - 22Mm X 22Mm X15Mm

The End Feed Reducing Tee (22mm x 22mm x 15mm) is a crucial capillary fitting designed to create a permanent, leak-proof reduction in pipe size on the straight-through section, while maintaining the larger size on the branch. This specific configuration allows a 22mm pipe (the branch) to be reliably taken off a main line that reduces from 22mm to 15mm through the body of the fitting. This is often used when a large branch is needed before the main flow reduces for smaller domestic distribution.

Technical Specifications and Flow Management
Main Run Connection 1: 22mm End Feed (Capillary)

Main Run Connection 2 (Reduced): 15mm End Feed (Capillary)

Branch Connection (End): 22mm End Feed (Capillary) 90-degree outlet.

Configuration: Reducing Tee – Reduces the size of the straight run (22mm to 15mm) while maintaining a large 22mm branch.

Function: Provides a robust, permanent 22mm branch from a 22mm main line that is stepping down to 15mm.

Standard Compliance: Manufactured to meet the high standards of BS EN 1254-1, ensuring product quality, performance, and compliance.

Material: High-Quality Copper.

The Installer's Advantage for Zoned Systems
The 22mm x 22mm x 15mm reducing tee is valuable in zoned heating and plumbing systems where a larger branch is required before the main system reduces pipe size for smaller circuits. Using the permanent and secure capillary soldering method guarantees system integrity under pressure and temperature fluctuations.
