Generally, platinum cured silicones will have better tensile strength and elongation properties than peroxide cured silicones. However, peroxide cured silicone usually has better compression set properties for gaskets requiring critical long term sealing at extended temperatures. Therefore – both of these silicone product families have their benefits.

These gaskets are manufactured to the highest standards in a variety of sizes, materials and styles to suit all your needs. They are certified to US Pharmacopoeia Class VI-XXII, Cytotoxicity Criteria, Title 21CFR177.1550 & .2600 and USDA & 3A Sanitary Standards. The shelf life of rubber gaskets/O-rings is the period from curing to the date it is put into use in an application. Shelf life is retained as long as it is stored in a 65° to 85° clean, dry warehouse in the original package away from sunlight and electric motors.

Shelf Life:
• Buna-N - 10 Years
• EPDM - 10 Years
• Silicone - 5 Years
• FKM (Viton®) - 10 Years
• PTFE (Teflon®) - 20 Years
