For snow melt applications, use larger PEX tubing sizes, such as 5/8" and 3/4".

Ask a Question
What is ID of the pipe? Compared to the hydraulic line, it is more flexible or rigid?
Helpful? Yes No
The ID of 1/2" PEX tubing is ~0.475". The tubing flexibility slightly changes with air temperature - it is softer when the air is warmer and more stiff when air is colder. Overall, the 1/2" PEX tubing can be bent to a loop with a radius of 5".
