NSF SEAL

Manufacturers, regulators and restaurant operators look to NSF International for the development of public health standards and certification programs that help protect the world’s food, water, commercial and consumer products, and the environment. As an independent, accredited organization, their standards group facilitates the development of standards, and the service groups test and certify products and systems including all sorts of restaurant equipment and accessories. They also provide auditing and risk management solutions for public health and the environment.

A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a pump system), maintaining temperature, containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets or o-rings.
