End Feed Copper Pipe Fittings | 6.35mm to 76mm | Plumbing & Gas DIY

Match the fitting's outer diameter (Φ) to your existing copper pipe's nominal size. For reference, Φ15mm (≈9/16") is typically used for domestic water supply, Φ22mm (≈7/8") for main branch lines, and Φ28mm (≈1-1/8") or larger for commercial or high-flow applications. Always measure your pipe's outer diameter with calipers before ordering to ensure a proper capillary fit.

Center distance refers to the measurement between the centerlines of the two pipe ports on the fitting. This is important when planning tight installations where the spacing between parallel pipe runs matters — for example, in manifold banks or back-to-back connections. Select the center distance that matches your layout requirements.

Copper end feed fittings are generally rated for working pressures suitable for residential and light commercial plumbing — typically up to 150 psi (≈10 bar) for water systems when properly soldered. Actual pressure ratings depend on pipe size, wall thickness, and installation quality. Contact us to confirm ratings for your specific application.

Copper is naturally corrosion-resistant and is commonly used in outdoor plumbing and underground installations. In most cases, these fittings perform well in damp or exposed environments. For highly acidic soils or aggressive water chemistry, consult a licensed plumber to confirm suitability for your specific conditions.

End feed fittings are designed for capillary soldering — no threads are involved. They are generally compatible with standard lead-free solder and flux used in potable water systems. Ensure the pipe OD matches the fitting bore for a proper capillary joint. Always clean pipe ends and fitting sockets before soldering.

Copper fittings are commonly used for gas installations in many regions. However, gas work typically requires compliance with local codes and must be performed by a licensed professional. Always verify local regulations before using copper end feed fittings on gas lines. We recommend consulting a certified gas engineer for any gas plumbing project.

Thicker walls (e.g., 1.5mm, 1.8mm, or 2.2mm) generally provide greater durability and are better suited for higher-pressure or commercial applications. Thinner walls (0.8mm–1mm) are typically sufficient for standard residential water supply lines. See variant options for available wall thicknesses per pipe size, and contact us if you need guidance for a specific pressure rating.

We offer packs of 1, 2, 3, or 10 pieces. For a single repair or small DIY job, 1–2 pcs is usually sufficient. For larger copper pipe plumbing projects or to keep spares on hand, the 10-piece pack offers better value per unit. Mix and match sizes by adding multiple variants to your cart.
