Fuel Quick-Connect Seals

Help improve fuel system reliability with fluorosilicone rubber quick-connect seals

Choose proven Silastic® brand fluorosilicone rubber (FSR) elastomers and easy-to-process Silastic® brand fluoro liquid silicone rubber (F-LSR) elastomers for reliable fuel-system quick-connect seals.

Dow Corning high-performance fuel-system sealing solutions:

• Resist fuels, oils and solvents that degrade and destroy most organic elastomers.
• Maintain strong physical properties even with extreme heat or cold.
• Provide custom compounding options to optimize fuel resistance and minimize swelling in direct fuel contact.

Gain fuel and oil resistance plus processing economy
Both types of Silastic fluorosilicone elastomers are proven performers and ideally suited for fuel quick-connect seals.

• Solutions based on F-LSR and higher-hardness co-polymers are in a class alone for fuel system sealing.
• FSR and F-LSR offer an excellent combination of material performance, economical processing options, value and product selection range.

Fluoro liquid silicone rubber (F-LSR) offers advantages
Silastic F-LSR elastomers provide you with both design flexibility and processing economy:

• Simplify manufacturing of small parts needing fuel resistance.
• Injection molding boosts productivity and lowers per-unit costs.
• Over-molding can reduce inventory, labor and handling costs, reduce scrap rates.
• 100% F-LSR provides much longer part life in harsh environments than most partially fluorinated materials.
