Adaptors

Top Quality, Low Cost Adaptors

We have an extensive range of adaptors and reducers available to fill any need. These adaptors allow you to connect the various parts of your central heating system (pipes, valves and radiators) to each other.

  • 505 Microbore Adaptors: These are used to make a 15mm inlet smaller to correspond with 10mm or 8mm pipework.
  • 506 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.
  • 506 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.
  • 506 22mm Compression Adaptors: This adaptor is used to increase the size of a 15mm inlet to a 22mm inlet to suite the pipework.

These adaptors 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.
