PEEK tubing | Various ID and OD sizes. High pressure zones.

Our PEEK tubing is extruded from virgin PEEK. We do not add any additives to the original PEEK material except for color particles in the solid-color tubing.

  • Solid colored PEEK tubing is common for everyday use in HPLC as it’s chemically resistant and flexible. Tolerance is +/- 0.05mm for both ID and OD. Most economical

  • Striped colored indicator PEEK tubing consists of natural PEEK with a color stripe added to the outside only of the tubing after extrusion. We recommend using striped or natural tubing, as PEEK is not stable to all chemicals. Some solvents may react with the PEEK wall material and dissolve the color particles; this is an indication the tubing should be replaced. Tolerance is +/- 0.05mm for both ID and OD.

  • Ultra-T™ PEEK tubing is recommended when the flow volume precision is desired and is critical. This tubing is not normally used in typical HPLC systems; it is mostly used for LCMS, capillary LC and other applications that allow for little variation in flow dynamics. Tolerance is +/- 0.025mm for both ID and OD.
