Description

When you’re swapping out spray tips on your boom, a worn or damaged seat gasket can turn a quick job into a headache. Chemical leaks around the cap threads, inconsistent spray patterns, and dripping that wastes expensive chemicals—none of that’s what you want when you’re trying to get crops sprayed efficiently. This EPDM rubber seat washer creates the tight seal you need to keep everything working smoothly.

What You’re Getting

Chemical-resistant EPDM material that stands up to herbicides, fungicides, and fertilizers without breaking down
Perfect seal between cap and nozzle body to prevent leaks and maintain proper pressure
Designed specifically for Hardi retrofit cap applications without TeeJet strainers
Flexible rubber construction that compresses evenly for consistent sealing

Built for Real Spray Work

This gasket is made for the demanding world of crop spraying where chemicals, temperature changes, and constant vibration put serious stress on every component. Whether you’re running a self-propelled sprayer through corn fields or pulling a boom behind your tractor for pasture applications, this seal keeps your spray system operating at peak performance.

Made to Last

EPDM rubber is the go-to material for agricultural spray applications because it resists chemical breakdown and stays flexible through hot summers and cold springs. Unlike cheaper rubber compounds that get brittle or swell up in chemicals, this washer maintains its sealing properties season after season.

Good to Know

This particular washer is designed for use in Hardi retrofit caps without strainers, so double-check your setup before ordering. When installing, make sure the old gasket is completely removed and the sealing surfaces are clean—any debris or chemical residue can prevent a proper seal. A light coating of compatible lubricant on the threads makes assembly easier and helps prevent galling.
