LLDPE coolant tube, 10 mm outside diameter and 7 mm inside, in blue. Sold by the metre and supplied as one continuous length.
The small bore plumbing in a conversion, the runs that feed a heater core, a header tank or a degas line, does not need reinforced rubber hose. It needs something that holds pressure, takes coolant chemistry, and fits push fit fittings.
The 10 mm outside diameter is what fittings are sized on. Push fit connectors, elbows, tees and bulkhead fittings are specified by OD, so this goes straight into standard 10 mm fittings including Speedfit type push in connectors, our coolant tube Y adapter and bulkhead fittings.
Blue rather than natural is a labelling decision. Using one colour for one circuit, or one colour for coolant and another for something else, makes a loom readable months later when nobody remembers which line went where.
Know its limits. LLDPE suits cold and intermittent hot water service. It is not suitable for compressed air above 10 bar, nor for mineral oils, gases or fuels.

- Strong but flexible, so it routes by hand without heat forming
- Blue, so circuits can be told apart at a glance
- Cut to your length and supplied unbroken
Compatibility
For small bore coolant and fluid runs: heater circuits, degas and header tank lines, and any low pressure run needing 10 mm push fit. Works with Speedfit style push in fittings, our coolant tube Y adapter and bulkhead fittings.
This is small bore tube, not a main coolant hose. A 7 mm bore will not carry pump flow for a battery or motor loop. Those want proper coolant hose in a much larger size.
Cut it square. A push fit fitting seals on the outside of the tube, so a ragged or angled cut leaks. Use a tube cutter rather than snips.
