Adaptors

Top Quality, Low Cost Adaptors

We offer a vast range of adaptors and reducers ready to help you connect your brand new column radiator to the rest of your central heating system. These adaptors are used to connect the distinct parts of your system (pipes, valves and radiators) to each other.

    • Microbore Adaptors: These are used to make a 15mm inlet smaller to correspond with 10mm or 8mm pipework.
    • 3/4" to 1/2" Adaptors: This adaptor is used to decrease the size of a 3/4" connection to a 1/2" connection to correspond with 1/2" pipe work. These are available as a Single or a Pair.
    • 3/4" Couplers: These are used to increase the size of a valve outlet from a 1/2" outlet to a 3/4" outlet to fit a larger radiator outlet. These are available as a Single or a Pair.
    • 22mm Compression Adaptors: This adaptor is used to increase the size of a 15mm inlet to a inlet to suit the pipework.

These adapters are available in a variety of finishes, allowing you to customise many of the valves we sell to suit your needs.

If you need any advice please check our Buying Guide or call a member of our friendly Sales Team.
