Copper Endfeed Long Shank Reducers (15mm x 8mm / 10mm)

Execute ultra-compact transitions and low-profile layout modifications across residential heating networks with our premium copper endfeed long shank reducers. Known across the trade as extended street reducers, these components feature an elongated male insertion end (the shank) designed to pass entirely over a pipe run or seat deeply within a standard fitting socket. By converting any 15mm socketed fitting directly into an 8mm or 10mm micro-bore receiver, they eliminate the need for short intermediate pipe bridges, significantly reducing physical layout footprints behind modern radiators, partition walls, and manifold cabinets.

Manufactured from high-purity, heavy-gauge copper, each fitting provides excellent thermal mass to ensure rapid, uniform capillary draw during endfeed soldering.

📐 Sizing & Variant Selection

Select the specific variant from the dropdown menu to match your system criteria:

• 15mm x 8mm : Ideal for transitioning standard lines down to ultra-low profile 8mm micro-bore radiator loops

• 15mm x 10mm : Perfect for connecting high-efficiency central heating manifolds directly to standard 10mm feeds

🛠️ Key Features

• Extended Long Shank: Features an elongated male insertion profile engineered to seat fully inside preceding fitting cavities

• Seamless Size Reduction: Drop down smoothly from a 15mm infrastructure socket to micro-bore sizing without adding system length

• Pure Copper Build: Highly durable, corrosion-resistant composition built for long-term system reliability in closed wet loops

• Category: Endfeed / Couplers / Reducers / External / Long

💧 Plumbing & Installation Benefits

• Maximum Space Optimization: Bypasses standard external couplings, allowing intricate zone valves and distribution clusters to sit completely flush

• Turbulence-Free Transition: Precision-tapered internal shoulder architecture ensures smooth fluid transfer without creating air pockets or pressure restrictions

• Labor & Component Efficiency: Streamlines retrofitting by converting existing fitting sockets directly into localized feeds, cutting down on components and potential joint leak paths

• High Thermal Responsiveness: Lightweight design absorbs torch heat rapidly, protecting surrounding building materials, valves, and components from thermal fatigue
