Silicone O-Rings (VMQ) 70 Duro FDA 

A reliable, FDA-compliant sealing solution developed for food, beverage, dairy, and sanitary applications where temperature extremes and cleanliness are primary concerns. These VMQ silicone O-rings meet FDA 21 CFR 177.2600 requirements and are formulated to remain flexible and stable across a broad temperature range, from cold processing to hot washdowns.

In real-world use, FDA silicone 70 duro O-rings are commonly installed in pumps, valves, fittings, fillers, and processing equipment that experience frequent temperature changes, steam exposure, or thermal cycling. Silicone’s inert nature helps resist taste and odor transfer, while the 70 durometer hardness provides dependable sealing without excessive compression force.

They are an excellent choice for customers who need FDA food contact compliance, thermal stability, and clean sealing performance, especially in applications where Buna-N or EPDM may harden, lose elasticity, or shorten service life under temperature stress.
