Description
The DU-BRO Replacement Fuel Tank Stopper is an easy and reliable way to update or repair your DU-BRO fuel tank. If your tank stopper has hardened, cracked, or is no longer sealing properly, this replacement part restores your tank to safe, leak-free operation in just minutes. It fits any 2 oz to 50 oz DU-BRO fuel tank, making it a universal solution for many different RC aircraft.
DU-BRO offers two stopper types so you always get the correct one for your fuel system:
-
Brown Stopper – For Gasoline
-
Black Stopper – For Glow Fuel
Each stopper is made from a specially formulated material designed to resist the type of fuel it’s intended for. Glow fuel and gasoline affect rubber differently, so using the right stopper ensures long-lasting performance and helps prevent leaks, air bubbles, and unreliable engine operation.
Replacing your stopper is simple: remove the old one, insert the new stopper, tighten the cap, and reconnect your fuel tubing. In just a few minutes, your fuel tank is ready to go with a clean, fresh seal you can trust.
This replacement stopper is ideal for:
-
Older tanks that need maintenance
-
Tanks being converted between glow and gas
-
Fixing leaks or loose-fitting stoppers
-
Ensuring safe, consistent fuel delivery
Proudly Made in the USA, the DU-BRO Replacement Fuel Tank Stopper is a small but essential part that keeps your RC fuel system running smooth, strong, and dependable on every flight.
