### Access the Calculator

## Easily Account for Thermal Expansion and Contraction in System Design

Thermal expansion and contraction is a property of all piping materials, including both metals and thermoplastics. If left unaccounted for in piping system design, it can cause compressive stress on pipe and fittings, resulting in damage to residential plumbing systems.

Using a deflection mechanism, such as an expansion loop, is recommended to easily account for thermal expansion and contraction and safeguard the pipe against potential damage.

## How the Expansion Calculator Works

Enter in your pipe diameter, maximum and minimum temperatures, and pipe length. From there the calculator will deliver required expansion loop dimensions in both feet and inches.
