This 140 mm white HVAC trunking protects and neatly covers insulated refrigerant pipework, condensate drains and control cable on air conditioning installations, and also suits air-to-water heat pump flow and return pipework. The 140 mm width takes insulated pipework and associated cabling together for a clean, professional finish.
It is made from stiff, shockproof anti-UVA PVC, so it shields the pipework from sunlight, weather, accidental damage and pests. The rounded cover closes with a central closure with accidental anti-release, and the base has pre-punched slots for wall mounting. Available as a 2 m straight length, 90° internal bend, 90° external bend and wall cover in white (RAL 9010).

⚠ Check the fit before you order
Measure the combined outer diameter of the insulated pipes, any condensate drain and the cable you plan to run inside, and check they fit within the 140 mm trunking. Internal depth is not published, so allow generous clearance.
⚠ Cables sharing trunking with pipework
Where electrical cables run in the same trunking as pipework, follow BS 7671 and the unit manufacturer's installation instructions. Refrigerant pipework must be installed and tested by F-Gas certified engineers before it is covered.
ℹ Installation tip
Fix the base to the wall through the pre-punched slots using fixings suited to the wall type, lay the pipework in, then close the rounded cover. The PVC is paintable if you want to match the wall colour.

Frequently asked questions
What fits inside the 140 mm trunking?
It is designed to take insulated flow and return pipework and associated cabling. For air conditioning that typically means an insulated refrigerant pair coil, a condensate drain and control cable, depending on pipe sizes. Measure the combined outer diameters and allow clearance.
Is the trunking UV resistant?
It is made from anti-UVA PVC, which is designed to resist degradation from sunlight on external runs.
Can I paint it?
Yes. The PVC is paintable, so you can match it to the wall colour.
What do the bends and wall cover do?
The 90° internal and external bends turn the run around internal and external corners. The wall cover finishes the trunking where it meets the wall.
How do I fix it to the wall?
The base has pre-punched slots for wall mounting. Use fixings suitable for your wall type, then close the rounded cover over the pipework.
What temperature range does it cover?
The operating temperature range is −20 °C to +60 °C.
