Brass Olives

Brass olives are the sealing ring that lets you make or remake a compression joint without soldering, so they are a practical choice when you want a clean mechanical connection and the option to dismantle the fitting later. This range is aimed at compatible compression fittings across common pipe sizes, making it useful for both planned installation work and straightforward repairs. If you are replacing an old joint, it is worth remembering that a previously compressed olive should not be reused.

The key decision is size. You need to match the olive to both the pipe and the compatible compression fitting, and this collection covers a broad spread from smaller sizes such as 6mm and 8mm through common 10mm, 12mm, 15mm, 22mm and 28mm options, up to larger 35mm, 42mm and 54mm sizes. There are also conversion olives in selected sizes, which can be useful where the fitting design calls for that specific format rather than a standard olive.

Material choice matters too, but brass is not automatically better than copper in every job. Brass is generally firmer and less malleable than copper, and some products use design details intended to control how the olive deforms and grips the pipe. The sensible approach is to choose the olive type that suits the fitting design, the joint you are making and any manufacturer guidance for that compression system.

Pack quantity can make a real difference to value and convenience. In this collection you will find trade-friendly packs for repeated jointing work, along with smaller quantities that can make more sense for occasional repairs or larger-size pipework used less often. That helps you avoid overbuying for a one-off job while still keeping common sizes on hand for regular work.

Across the range, you will also see specification details such as compression connection type, relevant standards and WRAS approval where recorded for the individual product. Some products in the wider range also carry application information for water or gas, but that should always be checked at product level rather than assumed across every olive here. If you are choosing across materials or sizes, start by matching the pipe and fitting correctly, then pick the pack quantity that suits the amount of jointing work you have planned.
