Description
When you’re mixing chemicals or filling your sprayer tank, the last thing you want is liquid splashing back out or air bubbles interfering with your pump. This 5-inch tank lid with a built-in ball check valve solves both problems by letting liquid flow in while preventing backflow and keeping air from getting trapped inside your tank.
What You’re Getting
- Built-in ball check valve prevents backflow and eliminates air pockets during filling
- Precision-molded poly construction stands up to chemicals and UV exposure
- Standard 5-inch diameter fits most sprayer tanks and poly storage tanks
- Secure threaded design creates a leak-proof seal that won’t work loose
- Replaceable gasket ensures long-lasting performance season after season
Built for Real Farm Work
This lid works perfectly on sprayer tanks, mix tanks, and chemical storage applications where you need controlled flow. Whether you’re running a 3-point sprayer, trailer unit, or ATV-mounted tank, this lid handles everything from herbicides to liquid fertilizers without breaking down or corroding.
Made to Last
Farm chemicals are tough on equipment, but this lid is molded from chemical-resistant polyethylene that won’t crack, fade, or deteriorate even after years of exposure to harsh agricultural products. The ball check mechanism is built to handle thousands of cycles without wearing out.
Installation Notes
This lid threads directly onto tanks with a standard 5-inch opening. The ball check valve works automatically—no adjustments needed. If your old gasket is cracked or hardened, you can order a replacement separately. A light coating of grease on the threads makes future removal easier.
