Introduction to PEX Piping Types
PEX is flexible piping made from cross-linked polyethylene. It’s changing the way plumbing is installed in homes and buildings.
PEX is different from metal pipes. It bends easily around corners and tight spaces.
This flexibility means fewer connections are needed. As a result, plumbing systems become more efficient.
There are two main types of PEX: PEX A and PEX B. Each type is made differently.
These differences affect how they work and how long they last. Plumbers can choose the best pipe for each job.
PEX has made plumbing better. It doesn’t rust and can handle hot and cold.
PEX is lighter than copper or steel pipes. It lasts a long time and is easy to install.
Key Differences Between PEX A and PEX B
PEX A and PEX B pipes differ in how they’re made. PEX A uses the Peroxide method, making it more flexible.
PEX B uses the Silane method, which results in a stiffer pipe. The way PEX B is made affects its ease of installation.
PEX A is better for tight spaces. It can handle extreme temperatures better than PEX B.
PEX A has a more uniform structure. This may make it more durable over time.
Experts often pick PEX A for important plumbing jobs. Knowing these differences helps people choose the right pipe.
