Description
When you’re dealing with a leaky tank drain, nothing ruins a day of spraying or liquid fertilizer application like having chemicals drip all over the place. A worn gasket on your bottom drain flange might seem like a small thing, but it can lead to product waste, environmental concerns, and a mess you definitely don’t want to deal with. This replacement gasket gets your tank sealed up tight so you can focus on getting the job done.
Key Features
- EPDM rubber construction that handles agricultural chemicals, fertilizers, and temperature swings without breaking down
- Full gasket design provides complete sealing around the entire drain flange connection
- Fits multiple flange sizes – works with 3/4 inch, 1 inch, and 1-1/4 inch bottom drain flanges
- Chemical resistant material won’t swell, crack, or deteriorate when exposed to common farm fluids
- Direct replacement part that installs without modifications or special tools
Built for Real Farm Work
This gasket is designed for the bottom drain flanges commonly found on sprayer tanks, liquid fertilizer applicators, and other agricultural equipment that handles chemicals and liquids. Whether you’re running a pull-type sprayer, self-propelled unit, or nurse tank, keeping those drain connections sealed is critical for safe operation and preventing costly product loss.
Made to Last
Farm chemicals and fertilizers can be tough on rubber seals, but EPDM material is specifically chosen for its resistance to these harsh conditions. This gasket maintains its flexibility and sealing properties even after exposure to herbicides, pesticides, liquid fertilizers, and the temperature extremes you’ll see from season to season.
Good to Know
Before installing the new gasket, clean both the flange surfaces thoroughly to remove any old gasket material or chemical residue. A little brake cleaner or degreaser helps ensure a good seal. Check that the bolts are in good shape too – corroded hardware can prevent proper compression even with a new gasket.
