Navigator MSL expands its Thorsys range with pre-insulated copper tubes designed for air conditioning, VRF, and split system HVAC installations.
Plumbing and HVAC distributor Navigator MSL has expanded its product catalog with the introduction of pre-insulated copper tubes under its Thorsys brand. The new line is manufactured from 99.9% Cu-DHP copper tube and features 9mm expanded closed-cell polyethylene insulation. To protect the pipework during transit and installation, the assembly is encased in a UV-resistant LDPE outer covering.
Targeted primarily at air conditioning, variable refrigerant flow (VRF), and split system installations, the factory-applied insulation provides an immediate alternative to lagging bare pipework on site. By delivering a pre-jacketed pipe, the product aims to reduce fitting times and improve consistency across refrigeration and cooling runs.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?
For heating, plumbing, and air conditioning engineers, this launch offers a practical way to streamline pipework installations. Purchasing pre-insulated tube eliminates the labor-intensive process of manually feeding insulation over long copper runs, cutting down on-site installation time. The integrated UV-resistant outer layer also provides essential protection for external pipe runs against degradation, reducing the risk of premature failure or heat gain on exposed split systems.
When purchasing from merchants, installers should verify that the 9mm closed-cell polyethylene insulation meets the specific thermal performance and building regulation requirements for their particular cooling or heating installation. While pre-insulated pipework typically carries a higher initial material cost compared to standard bare copper tube, the reduced labor time and cleaner finish often offset the higher upfront product spend on commercial and residential jobs.
The Thorsys pre-insulated copper pipe range is available through Navigator MSL’s network of national and independent trade merchants across the UK.
