High-Strength Multipurpose Neoprene Rubber Sheets, Bars, and Strips
This rubber has better shock absorbing qualities and will provide longer life than Standard Multipurpose Neoprene. Neoprene is also called chloroprene. It has good oil and abrasion resistance. Softer durometer rubber has better conformability; harder durometer rubber is more wear resistant.

High-Strength High-Temperature Silicone Rubber Sheets and Strips
Greater strength than standard High-Temperature Silicone translates into better shock-absorbing qualities and longer life. Silicone, commonly called polysiloxane, offers good resistance to ozone and salt water.

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.
Washers with a Fluoroprene fluoroelastomer seal have excellent chemical resistance and withstand high temperatures, so you can use them in steam sterilization. They are FDA compliant but are not 3-A certified and don’t meet NSF/ANSI standards.
