Polymer Tubing Instruction Guide

by IDEX Health & Science

This polymer tubing has been machine cut and may not be square on the ends. The thru-hole may also appear smaller than normal due to material shearing. We recommend you re-cut the tubing (with a tubing cutter) prior to use, ensuring a fully open thru-hole and clean, square cut. Additional length has been added for this purpose.

Important Warnings: We suggest you use caution when working with any polymer tubing under pressure.

  1. Always wear eye protection when in close proximity to pressurized polymer tubing.
  2. Extinguish all nearby flames if using flammable solvents.
  3. Please see the Polymer Chemical Compatibility Chart below.

Specific Cautions for PEEK Polymer Tubing:

  1. With high solvent flow rates, particularly with organic solvents, a static charge may build up on the surface of the tubing. Electrical sparking may occur.
  2. Do not use PEEK tubing that has been severely stressed or kinked.

1  Do not use the following: Nitric Acid; Sulfuric Acid, Halogenated Acids, such as Hydrofluoric Acid, Hydrobromic Acid, and Hydroiodic Acid (Hydrochloric Acid is approved for use in most applications); and pure Halogenated Gasses. Due to a swelling effect, use the following with caution: Methylene Chloride, THF and DMSO.

2   While the solvent compatibility of FEP & PFA is virtually identical, please note the temperature rating differences between them.

M  Some solvents in this category are satisfactory, others are not. Please review the notes above or contact IDEX Health & Science for further information.

R  Recommended.

NR  Not recommended.
