Straight lengths of Hep O Standard and Barrier pipe are supplied in 3m lengths in 15mm, 22mm and 28mm diameters. Straight pipe is just as flexible as coiled pipe and is primarily intended for exposed pipework where neatness is vital or where only a short length of pipe is required.
There are two main pipe materials on the market, Polybutylene (PB) and Cross-linked Polyethylene (PEX) and both have different properties.
PEX pipe is relatively stiff and when taken from the coil retains a spring-like quality, which can make it difficult to work with, particularly on long runs and when cabling through joists or floors.
Polybutylene, in comparison, is cured on massive drums, and the plastic memory means that when you uncoil it lays flatter, as seen in the image below. It’s also very flexible, so easy to work with in all situations. Hep O pipe is all PB.

A unique characteristic of Hep O pipe coil is its remarkable ability to remain straight once uncoiled, unlike some other plastic materials which act like a spring and makes handling so awkward that two men may well be required to carry out a relatively simple job. Hep O pipe is much easier to handle and much easier to cable because of its inherent tendency to stay where it’s put.
Coiled Hep O pipe is supplied in 25m to 100m coils, in 10mm, 15mm, 22mm and 28mm diameters, in a SmartPack™ dispenser.
