PEEK Tubing for HPLC

Build or replace a liquid chromatography flow path with PEEK tubing for HPLC. Flexible and easy to cut to length, PEEK tubing is used to connect components where a polymer fluid path is preferred. It offers a practical option for routing lines through an instrument without relying on stainless steel tubing throughout.

PEEK is compatible with many commonly used HPLC mobile phases, but solvent selection matters: some chemicals can cause it to swell. Tubing pressure capability also varies with its dimensions. Choosing the right tube is therefore as important as choosing the material.

Find the right tubing for your system

Check the internal diameter (ID) for your flow requirements and the outer diameter (OD) for a fit with your connections. Then compare the required length, pressure rating and solvent compatibility with the specification of the individual product.

Explore our PEEK HPLC tubing collection to find a suitable line for your chromatography setup, whether you are assembling a new flow path or replacing an existing section.
