Style FV200 - FVMQ Fluorosilicone Rubber O-ring

Blue FVMQ fluorosilicone o-rings are traditionally used elastomer seals that can meet a number of programs. The mechanical and physical properties are much like silicon rubber. fluorosilicone o-rings are becoming more widely well-accepted for standard purpose use. Having said that, blue FVMQ fluorosilicone o-rings are most commonly utilized in aerospace programs, especially with its good resistance to jet fuel. Fluorosilicone o-rings possess small abrasion resistance and are usually desired for use in static situations.

FVMQ fluorosilicone is the substance caused by the compounding of fluoroelastomer (FKM) as well as silicone. With fantastic compression set and also performance in large and small temperature conditions, fluorosilicone (FVMQ) is similar to area chains of silicone rubber, bonding trifluoropropyl, methyl as well as vinyl. The mechanical and physical properties are similar to VMQ Silicone. Having said that, FVMQ gives advanced petrol and nutrient oil level of resistance, however a smaller amount hot air resistance than normal VMQ Silicone.

FVMQ fluorosilicone o-rings typically are usually blue in color, with an boundless shelf-life.

FVMQ Fluorosilicone O-ring Characteristics

FVMQ fluorosilicone O-ring is normally utilised in the Aerospace field. This product is good for applications that require fuel or diester-based lubricant resistance nearly 204°C. Blue FVMQ fluorosilicone o-rings are generally specified for aerospace use. Even so, due to their outstanding fuel resistance and also higher temperature stableness, Fluorosilicone is now popular for a greater choice of sealing applications.

Fluorosilicone rubber materials offer you very good compression set as well as durability attributes. They are suitable for exposure to air, sunlight, Ozone, Chlorinated and aromatic hydrocarbons.

Usual Application of FVMQ Fluorosilicone O-Ring

Blue FVMQ fluorosilicone o-rings are often used in aerospace purposes for petrol systems and programs necessitating resistance to diester base lubricants to 175°C. And also for dry heat environments, broad temperature range environments, some petroleum oil applications and chlorinated solvents environments. Because of their poor physical characteristics they are normally only recommended for static purposes.

What is FVMQ Fluorosilicone O-Ring Temperature Range?

Primary uses of fluorosilicone O-rings are in fuel systems at temperatures up to +177°C (+350°F) and in applications where the dry-heat resistance of silicone O-rings are required. FVMQ Fluorosilicone O-rings may also be exposed to petroleum based oils and or hydrocarbon fuels. In some fuels and oils, the high temperature limit in the fluid list is more conservative because fluid temperatures approaching 200°C (390°F) may degrade the fluid, producing acids which attack fluorosilicone O-rings. For low temperature applications, FVMQ fluorosilicone O-rings seal at temperatures as low as -73°C
