Chemical Compatibility for Parker Parflex Plastic Tubing
The information below covers the chemical compatibility of Parker plastic tubing listed in Parker Parflex Catalog 4660, Edition 8/2014 (Thermoplastic & Fluoropolymer Products). This chemical compatibility guide must not be used in conjunction with any other compatibility guides from previous or future catalog editions, bulletins or publications. Plastic tubing chemical compatibility may change from time to time due to changes in manufacturing process. Incorrect use of these charts could result in personal injury, death or property damage.
How to Determine Chemical Compatibility of Parker Tubing with Listed Chemicals
- Locate the Material Code in the Material Code Table.
- Locate the media to be carried or the chemical the tubing will be exposed to in a Media to Plastic Tubing Material Compatibility Table and read the ratings code under the material column.
- Look up the rating code in the Rating Codes Table.

Chemical Compatibility Notes:
- The Fluid Compatibility Guides are simplified rating tabulations based on immersion tests at 75°F. Higher temperatures tend to reduce ratings. Since final selection depends on pressure, fluid and ambient temperature and other factors not known to Parker Hannifin Co., no performance guarantee is expressed or implied. Ratings do not imply compliance with specialized codes such as FDA, NSF, AGA or UL and do not cover possible fluid discoloration, taste or odor effects. For conveying foodstuffs, use FDA sanctioned materials. For potable water, use NSF listed materials. For chemicals not listed, or for advice on particular applications, please consult Parker Product Engineering, Parflex Division, Ravenna, Ohio.
- Hose applications for these fluids must take into account legal and insurance regulations. This does not imply AGA or UL compliance.
- Satisfactory at some concentrations and temperatures, unsatisfactory in others.
- For high pressure gases, the cover should be pinpricked and the pressure must not be released quickly. Chain or restrain the hose to prevent personal injury in the event of damage or failure.
- Chemical compatibility does not imply low permeation rates. Consult the Parker factory for a suggestion for your specific requirement.
- Does not imply NSF or FDA compliance.
- Chemical compatibility does not imply acceptability for use in airless paint spray applications. These applications require a special conductive hose.
- Fluoropolymers are chemically compatible with Anhydrous Ammonia. However, extreme caution must be used in dealing with Anhydrous Ammonia since it can cause severe injuries such as blindness and/or chemical burns.
3. Compatibility Ratings Codes Table:
|G||Good to Excellent - Little or no swelling, tensile or surface changes. Preferred choice.|
|L||Marginal or Conditional - Noticeable effects but not necessarily indicating lack of serviceability. Further testing suggested for specific applications. Long-term effects such as stiffening or potential for crazing should be evaluated|
|P||Poor or Unsatisfactory - Not recommended without extensive and realistic testing.|
|-||Not tested - Compatibility not known|
|#||For fluoroplolymer - Indicates good chemical resistance but potential for excessive permeation.|
