Description
When you’re swapping out spray tips or rebuilding nozzle bodies on your boom sprayer, this little EPDM seat washer might be small, but it does a big job. It creates the seal between your spray tip and the QuickJet cap that keeps chemicals where they belong—coming out the nozzle instead of leaking around the threads or dripping on your crops.
What You’re Getting
- EPDM rubber construction that resists chemical breakdown and temperature extremes
- Perfect fit for all TeeJet spray tips except the disc-core style tips
- Creates a reliable seal that prevents costly chemical waste and uneven spray patterns
- Direct replacement part that fits like the original factory washer
Built for Real Farm Work
This washer works with TeeJet’s QuickJet cap system, which you’ll find on boom sprayers across thousands of farms. Whether you’re running a small pull-type sprayer for spot treatments or a big self-propelled unit covering hundreds of acres, this seal keeps your spray system working properly when you’re applying herbicides, fungicides, or liquid fertilizer.
Made to Last
EPDM rubber holds up better than regular rubber when it comes to farm chemicals and weather. It stays flexible in cold weather and won’t crack or harden from UV exposure or chemical contact. This material is specifically chosen for agricultural spraying because it maintains its sealing properties season after season.
Installation Notes
When you’re changing tips, take a second to check this washer—if it’s cracked, hardened, or has chemical buildup, swap it out. A fresh washer only costs pennies but can save you dollars in wasted chemicals and ensure your spray pattern stays consistent across the field.
