7. Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of fluorosilicone over standard silicone tubing?
A: The key advantage is dramatically improved resistance to fuels, oils, solvents, and hydrocarbons. While standard silicone performs well with many aqueous and biological fluids, it degrades quickly in petroleum-based environments. Fluorosilicone rubber tubing maintains its integrity in these harsh conditions.
Q2: Can this tubing be used for permanent immersion in fuel?
A: It is highly resistant to continuous exposure to many fuels and oils within its rated temperature range. However, for permanent immersion in specific aggressive blends (e.g., high-aromatic or oxygenated fuels), we recommend consulting our technical team with the exact fluid and temperature profile for a compatibility verification.
Q3: Is fluorosilicone tubing suitable for food or medical applications?
A: Our standard grade is designed for industrial use. For applications requiring USP Class VI, FDA, or EC 1935/2004 compliance, we offer specially formulated, high-purity grades. Please inquire about our compliant formulations.
Q4: How does the price compare to FKM (Viton®) tubing?
A: Fluorosilicone rubber tubing is typically priced higher than standard FKM due to its specialized polymer chemistry. However, its superior low-temperature flexibility and sealing force often provide better performance and value in dynamic or low-temperature sealing applications, justifying the investment.
Q5: Do you offer custom colors and printing?
A: Yes. Custom colors for product identification or branding are available. We can also provide continuous stripe marking or custom printing (e.g., part numbers, safety warnings) on the tubing surface for traceability and compliance.
