End Feed Reducing Tee Fittings — Reliable Copper Pipe Connections for Every Plumbing Branch

When you're branching off a main copper pipe run to feed a radiator, basin, or secondary circuit, a poorly fitted tee can mean leaks, callbacks, and costly rework. Whether you're a professional plumber tackling a full heating system installation or a confident DIYer replumbing a bathroom, these WRAS-approved end feed reducing tee fittings give you a clean, soldered joint you can trust.

Each fitting is manufactured from copper and follows the standard end feed (capillary) design — you apply solder separately for full control over the joint. The reducing tee format is expressed as Run × Branch × Run (e.g., 22mm × 15mm × 22mm), where the two outer dimensions match your main pipe and the middle dimension is the reduced branch outlet. Sizes range from 8mm (≈5/16") up to 108mm (≈4-1/4"), with wall thicknesses from 0.7mm to 2.5mm scaled to each size. Available in single-piece or 5-piece packs.

These copper reducing tee fittings are suited for domestic hot and cold water supply lines, central heating and radiator circuits, underfloor heating manifold branches, and commercial plumbing pipework where a WRAS-compliant copper fitting is specified.

ℹ️ Compatibility: Designed for standard copper tube to EN 1057 (R220/R250). Fitting size format is Run × Branch × Run (e.g., 22mm × 15mm × 22mm). Confirm your pipe OD before ordering. WRAS approved for potable water systems.

✅ Key Features of These End Feed Reducing Tee Copper Fittings

  • 🔧End Feed (Capillary) Design — No pre-loaded solder; apply your own lead-free solder for a controlled, professional joint on copper pipe reducing tee connections.
  • 💧WRAS Approved — Certified under the Water Regulations Advisory Scheme, confirming suitability for potable (drinking) water plumbing systems.
  • 📐Wide Size Range — Covers 8mm through 108mm outer diameter, with branch reductions across the full range — ideal for copper pipe reducing tee branch-off applications in heating and water supply.
  • 🏗️Scaled Wall Thickness — Wall thickness increases with fitting size (0.7mm at 8mm up to 2.5mm at 108mm), providing structurally appropriate strength for each pipe diameter.
  • 🔁Flexible Pack Options — Available in 1-piece or 5-piece packs, so you can grab a single fitting for a repair or stock up for a full installation without overpaying.
  • 🌡️Copper Construction — Naturally corrosion-resistant and thermally conductive, copper fittings perform reliably in hot and cold water systems, central heating circuits, and underfloor heating pipework.

❓ Frequently Asked Questions

How do I choose the right fitting size for my copper pipe?

The fitting size is expressed as Run × Branch × Run (e.g., 22mm × 15mm × 22mm). Match the outer diameter of your copper pipe to the corresponding run dimension. The middle number is the reduced branch outlet. For reference: 15mm ≈ 19/32", 22mm ≈ 7/8", 28mm ≈ 1-1/8", 35mm ≈ 1-3/8". When in doubt, measure your pipe OD with calipers before ordering.

What wall thickness should I select?

Wall thickness is typically matched to the fitting size — smaller fittings (8–12mm) generally use 0.7–0.8mm walls, mid-range (15–35mm) use 1–1.3mm, and larger sizes (42–108mm) use 1.5–2.5mm. In most cases, selecting your fitting size will show the appropriate wall thickness. For high-pressure or commercial applications, contact us to confirm suitability.

Are these fittings approved for drinking water (potable water) systems?

Yes. These end feed reducing tee fittings are WRAS approved (Water Regulations Advisory Scheme), confirming they are generally suitable for potable water plumbing systems. Always verify compliance with your local plumbing code and use a WRAS-approved solder and flux for drinking water applications.

Can I use these copper fittings for central heating or underfloor heating?

Yes. Copper end feed fittings are widely used in central heating circuits, radiator connections, and underfloor heating manifold branches. Copper is naturally corrosion-resistant and handles the temperature ranges typically found in domestic and light commercial heating systems. For fully exposed outdoor installations, insulate the pipework to protect against freezing.

What solder and flux do I need for end feed fittings?

End feed fittings require you to apply solder separately (unlike solder ring fittings which have solder pre-loaded). Use a lead-free solder compliant with your local plumbing regulations, along with a compatible flux. For potable water systems, always use a flux and solder rated for drinking water contact. Clean the pipe and fitting socket thoroughly before soldering for a reliable joint.

What is the difference between an end feed fitting and a solder ring fitting?

An end feed fitting has no pre-loaded solder — you feed solder into the joint yourself during installation, giving you control over the solder quantity and joint quality. A solder ring (Yorkshire) fitting has a ring of solder pre-loaded inside the socket. End feed fittings are generally more economical and are preferred by experienced plumbers who want precise control over each joint.

How do I confirm the reducing tee will fit my existing pipework?

The size format is Run × Branch × Run. The two outer dimensions are the main run pipe connections; the middle dimension is the reduced branch outlet. Measure your existing pipe outer diameter (OD) with calipers and match to the fitting size. If you are unsure, contact us before ordering — we're happy to help confirm compatibility.

How many fittings do I need for a typical installation?

This depends on your pipework layout. For a single branch-off point (e.g., adding a radiator to an existing circuit), you typically need one reducing tee. For larger installations with multiple branch points, the 5-piece pack offers better value. We recommend ordering one or two spares for complex jobs where re-soldering may be needed.
