Plumbing accessory that makes adapting 10mm pipe into 15mm compression fittings straightforward, the HanaMoon Compression Olive Reducer Kit replaces standard olives with three brass reducer components. Peace of mind for engineers and DIYers who need a quick, reliable fix without special tools. Is it the right fit for your radiator or heating repair work?

⚡ At a Glance
  • Fitting Compatibility: Reduces a 15mm compression fitting to accept 10mm pipe securely
  • Best for: Plumbers, heating engineers and DIYers working on radiator and microbore systems
  • Not ideal for: Applications requiring permanent soldered joints or non-compression connections

Three brass reducer components adapt 15mm compression fittings to 10mm pipe sizes. Suited for radiator valves, heating systems and microbore plumbing work.


Secure microbore connections - with three brass reducer components

Each set contains three brass reducers that replace the original olive in a standard compression fitting, forming a tight mechanical seal around a 10mm pipe. The design keeps the compression action intact while adapting the fitting size.

Reliable joints reduce the risk of leaks when converting larger fittings to microbore pipework, ideal for radiator and heating repairs.

Durable performance - with corrosion-resistant brass construction

Brass resists corrosion and tolerates the temperatures commonly encountered in central heating systems, maintaining structural integrity over time. The metal's hardness helps the reducer retain shape under compression.

Long-lasting material means fewer replacements and less maintenance in wet, heated environments.

Tool-free swap-out installation - with olive replacement design

Reducers have the same form factor as standard olives and slot into compression fittings without the need for specialised equipment. Tightening the compression nut compresses the reducer against the pipe to form the seal.

Quick, straightforward installations save time on site and eliminate the need to carry extra tools or prepare soldered joints.
