Du-Bro 221 Silicone Fuel Tubing – Small, 2-Foot Glow Fuel Line

The Du-Bro 221 Small Silicone Fuel Tubing is a high-quality, flexible fuel line designed specifically for glow fuel-powered (nitro) RC engines. With a smaller inner diameter, this tubing is perfect for low-pressure applications such as clunk lines inside fuel tanks or tight routing around compact engines.

Made from premium silicone rubber, the DUB221 tubing remains soft, pliable, and fuel-resistant over time—resisting cracking and hardening commonly seen with lower-grade materials. It comes in a 2-foot length, ideal for replacing worn tubing or assembling custom fuel systems in RC planes, helicopters, boats, and cars.
