Description
Nothing ruins a good day of spraying like a leaky nozzle cap that’s dripping chemicals all over your equipment or letting air into the system. This little packing washer might not look like much, but it’s what keeps your TeeJet spray system sealed tight and working properly. When your nozzle starts weeping or you’re losing pressure, nine times out of ten it’s this washer that needs replacing.
What You’re Getting
- Stainless steel construction that won’t corrode from farm chemicals or fertilizers
- Precision-made seal that creates a leak-proof connection between nozzle components
- Direct replacement part that restores factory-tight sealing performance
- Durable material that maintains its shape under pressure and temperature changes
Built for Real Farm Work
This washer is designed to work with TeeJet’s professional spray nozzle systems—the same equipment you’ll find on sprayers from boom rigs to spot sprayers. Whether you’re applying herbicides, fungicides, or liquid fertilizer, this washer keeps everything sealed up so your chemicals go where they’re supposed to go, not on the ground.
Made to Last
Stainless steel doesn’t break down like rubber washers do when exposed to ag chemicals. It won’t swell, crack, or get eaten up by the harsh stuff you’re spraying. This washer will keep sealing properly season after season, even when you’re running hot chemicals or operating in extreme temperatures.
Installation Notes
Replacement takes just a minute—unscrew the cap, swap out the old washer, and thread everything back together. Make sure the washer sits flat in its groove for a proper seal. If you’re replacing multiple washers on a boom, it’s a good idea to do them all at once so you don’t have to go back later.
