PEX Tubing Expansion Calculator

Calculate how much PEX tubing expands and contracts with temperature changes to plan loops, offsets, and expansion allowances.

Tubing Details
PEX-A is most flexible and has the highest expansion rate. PEX-B and PEX-C are stiffer with slightly lower expansion rates.

Temperature Range
Use the coldest installation temperature and the hottest operating temperature for the worst-case expansion calculation.
