What’s the Difference Between PPR and PEX Plastic Pipes

PEX pipes are very different from PP-R pipes. Most importantly, PEX pipes are engineered and used for very different applications. PEX pipes are manufactured in smaller dimensions for use in plumbing, residential fire safety, and radiant heating and cooling systems. PEX piping is flexible, which allows it to flex around corners and weave through tight spaces. It’s a highly useful material for certain projects. However, PEX pipes are not designed to handle the larger diameters and high pressure that PP-R piping systems are engineered for.
