What is Proposition 65?

Why you may see a warning on our products

Some gasket materials can contain components such as carbon black, nickel, chromium, and petroleum-based compounds. Handling or installation may lead to exposures regulated by Proposition 65. While our products are manufactured to precise standards and typical use is not expected to result in harmful exposure, we provide the warning to comply with California law and to support informed choice.
