Chemical Compatibility Information
For John Guest Products |
| |
Responsibility of Use
While John Guest® warrants their products against defects in manufacture or materials, it is the responsibility of any user/installer to ensure that fittings and related products are suitable for their application, that the installation is carried out correctly, and that the installation is properly maintained.
Chemicals
For use with chemicals or other potentially aggressive liquids, please refer to the John Guest® Chemical Compatibility Chart or consult technical support. John Guest® Super SpeedfitTM fittings are not to be used with explosive gasses, petroleum spirits, and other fuels or for central heating systems.
Cleaning and Sanitizing
For Acetal fittings, we recommend only the use of cleaners and sanitizing agents that are above pH4 and are low in hyperchlorate levels. Acetal fittings and parts that are cleaned and/or sanitized should be rinsed immediately with copious amounts of clean, neutral tap water to remove all traces of the cleaners. Details of which products incorporating Acetal are designated by the following John Guest® part number prefixes: PI, PM, CI, CM and RM. While polypropylene has different mechanical properties than Acetal, John Guest® Polypropylene Fittings and Valves (PP prefix) offer greater resistance to aggressive chemicals and can be cleaned by the same process as Acetal fittings.
