Sanitary Metal-Bonded Sealing Washers
Eliminate cavities under screw heads where contamination may occur.
Washers with an EPDM seal are FDA compliant, 3-A certified, and meet NSF/ANSI standards for food processing. However, they don’t handle high temperatures as well as washers with a Fluoroprene fluoroelastomer seal.
