Cost Savings

Innovative and streamlined manufacturing process offering best prices

Energy Efficient
Thanks to the closed cell structure and foaming process Durotan PEX Sanitary provides excellent thermal insulation. (Lambda = 0.032W/mK) reducing energy losses substantially.

Reliable & Durable
Quality materials and components manufactured to the highest standards providing long service life. In the event of the pipe casing being damaged, the fully bonded composite structure prevents longitudinally flow of water towards the connected buildings.

Reduced Excavations
Smaller outer diameters means narrower and shallow trenches, speeding up construction works and providing groundworks cost savings.

Flexible & Light
Lightweight construction and reduced bending radius provides superior flexiblility and easy handling, reduces installation times and protects against external damage.

First class materials resistant to corrosion and incrustation.

Fast & Easy to Install
Pipe coils are delivered in long lengths (up to 830m) reducing the number of underground joints required and consequently reducing installation times.

Complete Range of First Class Accessories
Wide range of first class fittings (press or compression). Tried and tested robust heat shrink joints providing long service life.
