Solvents and chemicals that should be avoided when using PEEK filters, tubing and fittings include:

- Nitric acid
- Sulfuric acid
- Halogenated Acids, including hydrofluoric, hydrobromic, and hydroiodic acids*
- Pure Halogenated gases
- Methylene chloride
- THF (Tetrahydrofuran)
- DMSO (Dimethyl Sulfoxide)

*Note that you can use Hydrochloric Acid, all other HPLC grade solvents and HPLC buffers with most applications of PEEK Tubing and Fittings.
