Description
When your spray tips start leaking or your pressure drops during application season, it’s usually the cap and washer assembly that’s given up. A worn washer or cracked cap means uneven spray patterns and wasted chemicals—problems you don’t need when you’re trying to get crops covered efficiently. This replacement cap and washer assembly gets your nozzles sealing tight again so you can focus on getting the job done.
What You’re Getting
- Complete cap and washer assembly that seals spray tips properly against pressure loss
- EPDM rubber washer that handles farm chemicals without breaking down or swelling
- Durable construction designed to withstand the vibration and impacts of field spraying
- Quick-change design lets you swap caps and washers without tools in seconds
Built for Real Farm Work
This assembly works with TeeJet flat spray tips—the workhorses of field sprayers and boom applications. Whether you’re applying herbicides, fungicides, or liquid fertilizer, these caps keep your tips performing consistently across varying field conditions and spray pressures.
Made to Last
The EPDM washer material resists swelling and degradation from agricultural chemicals, while the cap construction handles the constant pressure changes and vibration that come with field spraying. This is the same quality TeeJet has been putting on spray equipment for decades.
Good to Know
Installation is straightforward—just unscrew the old cap, replace the washer if needed, and thread on the new assembly. Keep a few spare washers on hand since they’re the wear item in the system. If you notice uneven spray patterns, check the washer first before assuming you need a new tip.
