NSF, 3A Sanitary & FDA Approved O-Rings
All SPEC SEALS products are built to the highest national and international safety standards. Our rigorous adherence to these industry and governmental standards ensures the highest-quality O-Rings and custom-molded products delivered to distributors and manufacturers.
SPEC SEALS has recently developed two unique compounds specially formulated for potable water applications requiring NSF Standard 61 Approval.
NSF Standard 61 Approved Orings
The NSF Water Distribution Systems Program is responsible for the certification of drinking water treatment chemicals and drinking water system components to ensure that these products do not contribute contaminants to drinking water that could cause adverse health effects.
NSF Standard 61 Drinking Water System Components – Health Effects is the nationally recognized standard for all devices, components and materials which contact drinking water.

3A Sanitary Approved Orings
This standard is formulated by the International Association of Milk, Food and Environmental Sanitarians, U.S. Public Health Service, and the Dairy Industry Committee. These sanitary standards cover rubber materials intended for multiple-use as product contact surfaces or solution contact surfaces in the production, processing and handling of milk or milk products. Test procedures and criteria are also provided for rubber materials as a means of determining their ability to be cleaned and to receive effective bactericidal treatment or steam sterilization and to maintain their essential properties.

WRAS Approved Orings
Water Regulations Advisory Scheme (WRAS) is responsible for the water fitting testing and approval process in the United Kingdom. This organization specifies performance criteria and test procedures designed to verify compliance to British standards for product use with water fittings.
|E363-70||WRAS Approved for use in British and UK water fittings||-65 to +300F||70||Black|
KTW Approved Orings
KTW Guidelines are formulated by the German Technical Association for Gas and Water. These standards cover guidelines for organic materials that come into contact with drinking water intended for human consumption. Test procedures and migration criteria are provided in the KTW guidelines as a means of determining whether a material meets threshold heath, odor and flavor requirements.
