    Couplings

    Couplings – End Feed Fittings are soldered connectors used to join two sections of copper pipe in plumbing and heating systems, providing a compact, leak-free connection.

    About Couplings – End Feed Fittings

    End feed couplings are basic yet essential plumbing fittings that connect two lengths of copper pipe in a straight line. They are commonly used in domestic and commercial pipework for water, heating, and gas distribution (where permitted). Installation is done using solder and flux, creating a reliable, permanent seal.

    Due to their small profile and affordability, end feed couplings are frequently preferred for new installations, repairs, and system modifications.

    Benefits

    • Cost-effective: One of the most economical pipe connection methods.
    • Compact design: Ideal for confined spaces and discrete installations.
    • Durable joint: When soldered correctly, offers long-term leak protection.
    • Versatile use: Suitable for hot and cold water, central heating, and some gas applications.
    • Smooth internal bore: Minimises flow restriction.

    Applications

    • Domestic and commercial heating systems.
    • Water supply pipework.
    • Cooling and exposure-free installations.
    • Solar thermal and renewable heating systems.
    • Gas installations (must meet relevant approval standards).

    Key Features

    • Straight coupling for pipe joining.
    • Made from copper or brass.
    • Available in a wide range of pipe sizes (e.g., 8mm, 10mm, 15mm, 22mm, 28mm, 35mm+).
    • Typically conforms to BS 864 and BS EN standards.
    • Requires use of flux and solder for fitting.
    • Compatible with potable water when WRAS approved.

    Installation & Technical Info

    To install, pipes must be cut clean, deburred, and cleaned. Apply flux, insert into the coupling, heat, and apply solder evenly. Allow cooling before pressure testing.

    Use appropriate solder type depending on application (lead-free for potable water). Always ensure compliance with local plumbing regulations and standards.
