For specific chemical resistance information, please check the chemical resistance chart at the end of the section, or ask for specific recommendations.</p>\n\n\n\n<p class=\"alignwide mb-sm wp-block-paragraph\">Rilsan Nylon 11 is both WRAS and DWI approved, is suitable for use with potable water and has a maximum operating temperature rating of 90°C (195°F) for water service.&nbsp; It also meets the requirements of WIS 4-52-01 Part 1 and EN 10310.</p>\n\n\n\n<p class=\"alignwide mb-sm wp-block-paragraph\">Site repair of localised surface damage, e.g. through careless handling, is straightforward using the Rilsan Repair brush.</p>\n\n\n\t\t<div class=\"block-button custom-block left text-left\" id=\"block_74b317a1866f2bc7043188226582680e\">\n\t\t\t\t\t\t\t<a aria-label=\"Learn
