DU-BRO Tygon Gasoline & Diesel Tubing – Durable RC Fuel Line

The DU-BRO Tygon Gasoline/Diesel Tubing is a tough, long-lasting fuel line specially designed for gasoline and diesel-powered RC engines. Unlike standard silicone tubing used for glow fuel, Tygon tubing is built to withstand the chemicals and oils found in gas and diesel fuels. It stays flexible, resists cracking, and won’t harden over time—ensuring your fuel system stays reliable and leak-free.

This tubing is perfect for RC aircraft, cars, boats, and any model that runs on gasoline or diesel. It’s also an excellent replacement fuel line for string trimmers, weed trimmers, chainsaws, and other small gas-powered engines, making it a versatile choice for hobbyists and homeowners alike.
