TC Bros. Aluminum Filler Cap
You touch your fill cap every time you check your oil or put fuel in your tank. It would logically follow that the cap should perform reliably, open and close easily, and look dang good doing it. Evidently this one caught your eye—just as it’s supposed to.

- Fits many chopper oil bags and gas tanks including tanks by Mooneyes and TC Bros.
- CNC-machined
- 6061 billet aluminum construction
- Knurled for positive grip
- Leak-free, replaceable sealing O-ring
- Classic dome top contour
- 100% made in USA
- Available vented or without vent
- Available with or without weld-in bung (1018 mild steel) for custom applications
This filler cap fits our round oil tank should you need a replacement, and it can also serve as a reliable, good-looking cap for many aftermarket oil and fuel tanks that feature the same thread pitch—and many do. And if you like the style but have a different cap (or maybe none at all), our weld-in bungs are a great way to add a fill port anywhere one is needed—the 1018 mild steel is easy to weld in most oil bags and fuel tanks.
The vented cap is a good option for oil bags with a remote-mounted filler or single-filler cap fuel tanks, and the unvented version is a better option if the cap sits close to the fluid in an externally vented vessel.
