4.5mm X 60mm S70 FDA Silicone (VMQ) 70 Duro O-Ring

Metric O-Rings - Cross Section "CS" X Inside Diameter "ID"

Silicone (VMQ) Durometer 70 - Brick Red - FDA

FDA Grade Silicone compound for food & medical applications. The term silicone covers a group of materials in which vinyl-methyl-silicone (VMQ) is often the central ingredient. Silicone elastomers as a group have relatively low tensile strength, poor tear and wear resistance. Silicone Rubbers are ideal for high and low temperature applications. Electrical properties are excellent and resistance to weathering and ozone attack is outstanding. Food Quality/FDA compliant for use in the food and pharmaceutical industries.
