FVMQ O-Rings

O-Rings

Fluorosilicone (FVMQ) O-rings offer reliable sealing performance where flexibility, fuel resistance, and temperature stability are critical. This hybrid elastomer combines many of the low-temperature benefits of silicone with enhanced resistance to oils, fuels, and chemicals, making it a strong choice for aerospace, automotive, industrial, and defense applications.

Features & Benefits

Wide Temperature Range

Provides reliable sealing from -100°F (-74°C) to 350°F (177°C).
Improved Chemical Resistance

Offers similar chemical resistance to FKM with added flexibility at low temperatures.
Highly Resistant to Fuels and Oils

Offers excellent resistance to fuel, mineral oils, and low molecular weight aromatic hydrocarbons.
Compliant

Fluorosilicone meets the Mil-DTL-25988 specifications and is resistant to jet fuel, making it suitable for military aerospace applications.

Design Specifics

Fluorosilicone O-rings are made from a specialized blend of silicone and FKM materials, combining the best attributes of both. The hybrid construction ensures that the O-rings perform reliably even under harsh environmental conditions, offering both durability and elasticity in sealing applications where other O-rings might fail.

How FVMQ O-Rings Work

FVMQ O-rings’ silicone component provides excellent low-temperature flexibility, while the FKM component contributes superior chemical resistance. As a result, they maintain their sealing capability across a wide range of temperatures and resist a variety of aggressive chemicals.
