Polymer Tubing Instruction Guide
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.
- Always wear eye protection when in close proximity to pressurized polymer tubing.
- Extinguish all nearby flames if using flammable solvents.
- Please see the Polymer Chemical Compatibility Chart below.
Specific Cautions for PEEK™ Polymer Tubing:
- 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.
- 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.
