Imperial-size copper is awkward to match up. A 5/16" tube and a 8mm fitting look almost identical and won't seal against each other. This coil is true 5/16" imperial (8mm) outside diameter, with a 22 gauge (0.7mm) wall, so you can match it to imperial fittings and existing imperial pipework.
The tube is soft (annealed) copper made to BS EN 12449, the standard for seamless round copper tubes for general purposes, in phosphorus-deoxidised copper (CW024A). The soft temper bends easily, and a 30m coil gives long continuous runs with no joints, which suits small-bore pipework where fewer joints is an advantage.
BS EN 12449 is a general-purpose standard, so check that the tube is suitable for your service before use. This coil is not refrigeration (ACR) tube, so use ACR tube to EN 12735-1 for refrigerant circuits. Gas work must be carried out by a suitably qualified, registered gas installer in accordance with the relevant standards.
If you need genuine 1/4" imperial copper tube, this coil gives you the right size in a single 30m length, so you're not joining shorter pieces or guessing at a metric substitute. The soft temper makes it easy to route, and the standard is clearly stated so you can check it suits the job.
