Professional Endfeed Copper Reducing Tee Fittings (15mm x 15mm x 8mm & 10mm Middle Branches)

Optimise your domestic heating and microbore plumbing networks with our professional-grade Endfeed Copper Reducing Tee Fittings. Specifically designed for applications where a standard 15mm mainline needs to branch off into a smaller distribution loop, these premium copper tees feature a reduced center branch to maintain system pressure and efficiency without the need for additional reducer fittings.

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 ideal trade choice for feeding radiator tails, manifold systems, and intricate central heating loops where space is restricted and maximum structural integrity is required.

Available Size Variants

• 15mm x 15mm x 8B (SKU: WBS114) | Retail: £1.1 Perfect for dropping down from a standard 15mm copper supply line to an 8mm microbore pipe, frequently utilized in caravan plumbing, low-volume heating loops, and specialized radiator configurations.

• 15mm x 15mm x 10B (SKU: WBS115) | Retail: £0.9 Engineered to transition seamlessly from a 15mm main run to a 10mm microbore branch, making it a staple component for modern residential radiator manifold installations.

Key Features & Plumbing Benefits

• Streamlined Reducing Branch: Features matching 15mm inline sockets with a precisely machined 8mm or 10mm center outlet, ensuring balanced fluid dynamics and eliminating unnecessary joints.

• Premium Deoxidised Copper: Manufactured from trade-grade copper components offering exceptional thermal efficiency, corrosion resistance, and a lifetime of reliable service.

• Optimized Capillary Sockets: Socket depths are manufactured to exact trade tolerances, maximizing capillary action to pull solder deeply and evenly for a flawless, airtight seal.

• Compact Void Profile: The slimline endfeed profile easily fits within shallow wall cavities, underfloor runs, and tight service voids where bulky compression fittings cannot fit.

Quick Bullet Points for Buyers

• Efficient Branching: Drops standard 15mm lines down to 8mm or 10mm microbore feeds without extra reducers.

• Solder-Ready Engineering: Clean, uniform sockets ensure quick fluxing, rapid heat transfer, and swift assembly.

• Multi-System Approved: Fully certified for residential central heating loops, hot/cold domestic water, and low-pressure gas lines.

• Trade-Rated Value: High-integrity plumbing components priced competitively at £0.9 and £1.1 for cost-effective project planning.
