While the human body can sustain weeks without food, it can go no more than days without water. Water is life. Through municipal water systems and the connected plumbing that delivers it, many people have ready access to the water they require for daily use. We are very fortunate to have access to this vital resource.

No matter whether derived from rivers, lakes, reservoirs, or aqueducts, water is purified before it enters into circulation for public consumption. However, introducing clean water into the distribution system doesn’t guarantee the delivery of safe water to the final consumer. There are plenty of opportunities for water to become tainted from leached contaminants as it travels through the system’s piping and infrastructure.

Contaminants which can pollute drinking (potable) water as it travels through the distribution structure include chemicals that can leach from the products, components, and materials used in the system. To ensure consumer safety, only materials certified as safe by a reputable certification agency should be used in the manufacture of joining and sealing products for drinking water applications.

There are three major standards that address the safe use of joining and sealing materials in drinking water applications within the USA and Canada. Certification of materials to these standards should be sought when specifying joining or sealing products for all potable water applications:

Safe Materials for Drinking Water Gaskets: AB-576 EPDM

Archaic demands for rubber gaskets were for non-certified red SBR (Styrene Butadiene).

An antiquated low-cost staple in the water industry from a time when product safety standards were not prevalent. Styrene has been identified by the US EPA (Environmental Protection Agency) as a possible human carcinogen. In addition, non-certified SBR gaskets can leach other harmful contaminants including benzothiazole, mercaptobenzothiazole, nitrosamines, and phthalates. Exposure to these compounds can cause health disturbances that range from minor to severe, depending upon the level of exposure.

To avoid these issues and ensure safety, CRG uses AB-576 EPDM from American Biltrite to manufacture gaskets and other sealing solutions which service drinking water applications.

Gaskets and sealing solutions fabricated from AB-576 EPDM have the following advantages:

Key technical specifications for AB-576 EPDM are given below:
