Poly Pipe Guide
The different types of Polyethylene Pipe in the market cause headaches for many people trying to figure out what pipe they need, or already have on their property and matching this up with the fittings they need.
Simple Explanation:
It’s a long story but to make it short, LDPE is only made in NZ and Australia. Its measurement is based on the internal size of the pipe, MDPE is made worldwide and is measured on the external diameter of the pipe. Horticultural Lateral Tube is used for connection of sprinklers and drippers. These pipes use different fittings, click on the links below to see what the fittings look like
