Water & Gas Mains MDPE Pipe & Fittings.

The range is available in SDR11, SDR13.6 and SDR17.6, in sizes 20mm to 63mm for black MDPE pipe, blue MDPE Pipe and for yellow gas mains MDPE pipe in 20mm to 560mm. We offer a full assortment and they are adaptable for fitment to Lead Polyethylene, Copper, PVC and Galvanised Iron.

Blue MDPE water mains pipe is used for water service connections between the supply mains to individual properties and for above ground services if the pipes are installed inside protective twin wall ducts. It shouldn’t be used for the conveyance of diesel , gas oil, gases or compressed air. The system is suitable for use with cold water (maximum temperature 20C) with a working pressure of up to 12.5 bar. Our pipe is produced from MDPE as opposed. MDPE has a higher long term stress and crack resistance than HDPE PE80.

Wondering what the difference between black and blue MDPE pipe is? We’ve written a guide here.

Can we improve?

There's nothing more important to us at Easymerchant than the opinions of our valued customers. So please, tell us, is there a product you wish we kept in stock? Is information unclear on the website? Please tell us!

After being let down by another online supplier I decided to give Easymerchant a try based on a recommendation from a friend. I've placed several orders for twinwall drainage over the past few weeks and they have not let me down once. They always answer the phone and happy to answer any questions. Highly recommend!
