Blue PE Tubing 10 mm Per Metre | Water Treatment

Blue polyethylene tubing 10 mm, sold by the metre

Connection tubing in polyethylene, 10 mm outside diameter, in blue. It pushes straight into push-fit fittings to the 10 mm metric standard, with no glue and no special tooling.

Metric 10 mm, not 3/8"

Do not confuse the two: 10 mm metric and 3/8" (9.52 mm) are separate standards. A 0.5 mm difference is enough to compromise the seal of a push-fit fitting, the tube seems to hold, but the collet does not grip properly and the leak shows up under pressure. Check the standard of your fittings before ordering.

Colour identification

Blue is the colour conventionally associated with treated or cold water. On an installation with several lines, feed, distribution, dosing, return, this identification prevents connection errors at assembly and during any later servicing.

The 10 mm diameter

10 mm offers a noticeably larger flow section than 6 mm or 1/4". It is used on lines where pressure drop matters: appliance feed, tank outlet, run to a draw-off point, water cooler and coffee machine circuits.

Sold by the metre

Sale by the metre suits repairs, short runs and site top-ups, without opening a full roll. For installations in series, the roll remains more economical per metre.

Installation

Cut the tubing square with a proper tube cutter for a clean section, then push it fully into the fitting up to the stop. Avoid tight bend radii close to fittings and keep the tubing away from heat sources. On a run exposed to light, choose black tubing instead, which blocks light and prevents algae growth.
