Professional Endfeed Copper Reducing Tee Fittings (22mm Mainline with 10mm & 15mm Branching Options)
Description
Streamline your heating zones and plumbing manifolds with our trade-grade Endfeed Copper Reducing Tee Fittings. Specifically engineered for systems built on a high-flow 22mm mainline, these premium copper tees allow you to branch off into localized distribution loops or drop down continuation runs efficiently, maintaining ideal system pressure without the need for multiple independent reducers.
Belonging to the specialized Endfeed/Tee/Middle category, these high-purity, deoxidised copper fittings are engineered to create permanent, leak-proof capillary solder joints. They are the standard trade choice for feeding domestic radiator circuits, multi-zone underfloor manifolds, and plant room header networks where space is confined and maximum structural wall integrity is required.
Available Size Variants
| Size Specification | SKU | Retail Price | Primary Application |
| 22mm x 15mm x 22B | WBS118 | £2.2 | Ideal for stepping down an inline continuation run to 15mm while maintaining a full 22mm high-flow branch line. |
| 22mm x 22mm x 10B | WBS119 | £2.8 | Perfect for tapping a direct 10mm microbore radiator tail line off a primary 22mm central heating supply main. |
| 22mm x 22mm x 15B | WBS120 | £1.3 | The industry standard for dropping a 15mm domestic water feed or radiator loop leg out of a primary 22mm distribution mainline. |
Key Features
-
Targeted Middle & Run Reductions: Precision-machined configurations allow complex branch zoning in a single joint, cutting down on component clutter in tight voids.
-
Premium Deoxidised Copper: Formulated from high-purity copper to ensure exceptional thermal efficiency, natural scale resistance, and structural longevity.
-
Turned Capillary Sockets: Socket depths and entry profiles are tuned to strict trade tolerances, optimizing capillary action to pull solder deeply and evenly for a flawless seal.
-
Low-Profile Endfeed Layout: The compact, lightweight design fits easily into shallow floor joists, ceiling voids, and dry-lined walls where compression fittings cannot accommodate.
Plumbing & Trade Benefits
-
Mainline Flow Preservation: Delivers smooth internal transitions to reduce fluid turbulence, preventing unnecessary system pressure drops across the main line.
-
Minimized Failure Points: By replacing multi-fitting reducer clusters with a single engineered tee, you reduce installation time and eliminate potential leak variables.
-
Multi-System Certified: Fully rated for high-temperature domestic heating layouts, potable hot/cold water mains, and low-pressure natural or LPG gas lines.
-
Cost-Effective Trade Scaling: Priced competitively from £1.3 to £2.8, offering contract-ready value for large residential or commercial infrastructure installations.
Quick Bullet Points for Buyers
-
Direct Mainline Branching: Eliminates intermediate step-down sockets and adapters.
-
Solder-Ready Engineering: Clean, high-tolerance sockets ensure fast fluxing and rapid heat transfer.
-
Rigid Compliance Rated: Meets all standard UK and European installation criteria for confident sign-offs.
-
Space-Saving Design: Maximizes routing neatness behind finished walls and under floors.
