Euro-style pump union, 25mm loose nut × 20mm male thread. Sold individually.
What it solves
Most modern replacement circulating pumps come with 25mm (Rp 1) unions, while a lot of older Australian solar hot water pipework is 20mm. This union bridges the two, so you can fit a current pump without re-piping.
Specifications
- Pump side: 25mm loose nut, Euro style
- Pipe side: 20mm male thread
- Quantity: 1 union
How many do I need?
A pump has a union at each end, so order two for a complete changeover unless only one side needs adapting.
Fitting note
The union seals on its washer, not the thread — make sure the washer is present and seated. Do not over-tighten; the loose nut only needs to pull the faces together.
