Environmental Sampling Tubing: How to Choose the Right Size & Material
Wednesday, February 11, 2026
From groundwater purging to vapor intrusion assessments, the tubing you choose can make or break sample quality, data accuracy, and even how smoothly your day goes in the field.
There are typically two criteria to go by when selecting the right tubing for the job:
Material (compatibility, durability, chemical resistance, flexibility)
Size (OD for fittings + routing, ID for flow and purge times)
This guide walks through the “why” behind the common tubing materials, including best applications for each kind, and how to avoid the classic sizing mistakes that lead to leaks, poor flow, or compatibility problems.
