Identify a common type of flexible piping used for fuel-oil delivery.

• A. Silicone hoses
• B. Flexible rubber or PTFE (Teflon) hoses
• C. Vinyl tubing
• D. Polypropylene tubes

Answer: (B)

Flexible rubber or PTFE (Teflon) hoses are commonly used for fuel-oil delivery due to their versatility and durability. These materials are able to withstand a wide range of temperatures and pressures, making them suitable for transporting fuel oils that may be subject to varying conditions in storage and delivery systems. Rubber hoses provide resilience and flexibility, allowing for easier handling and installation, while PTFE hoses are particularly resistant to chemical corrosion, ensuring compatibility with various types of fuel oils. This combination of flexibility and chemical resistance makes them ideal for safely delivering fuel without risk of leaks or degradation over time. Other materials, though they may serve specific purposes, do not offer the same combination of performance characteristics required for reliable fuel-oil delivery.
