Silicone Rubber O-rings (Q, MQ, VMQ O-rings, PVMQ O-rings)

Physically, Silicone O-rings are based on silicon, an element derived from quartz. Silicone O-rings have excellent heat, ozone and corona resistance, are very well dielectric stability. Silicone O-rings are resistant to many oils, chemicals, and solvents. The silicone O-rings possess the best flexible property at low temperatures, but it also have some weakness like low tensile strength, poor tear strength and wear resistance.

Service Temperature: Silicone O-rings work in service temperatures from -60 C to 225 C. Some special types silicone O-rings can be used in extreme temperature up to 300 C and down to -100 C.

Hardness:  25 to 90 Shore A are available.

Color: Black, brown, green, white, rust, yellow, blue, red, orange, transparent and gray are available, or any assigned color from customers.

Application: Silicone O-rings perform well under environmental and temperature extremes. They are usually applied in automotive and aerospace industries where flexibility and longevity are important. Silicone O-rings also have outstanding electrical insulating properties where applying strict performance standards are critical. The silicone O-ring is also a suitable for parts that need FDA approval for food handling equipment and appliances.
