Description

When you’re trying to maintain consistent spray pressure across your boom or during spot spraying, a reliable cap assembly with built-in pressure relief makes all the difference. This TeeJet cap assembly protects your spray system from pressure spikes while ensuring steady flow when you need it most. No more worrying about blown seals or damaged nozzles when the pressure gauge starts climbing.

What You’re Getting

Built-in 20 PSI pressure relief that automatically vents excess pressure to protect your system
Durable construction designed to handle daily exposure to farm chemicals and weather
Standard TeeJet threading that fits most spray gun and boom setups
Consistent pressure regulation that keeps your spray pattern uniform

Built for Real Farm Work

This cap assembly works with TeeJet spray guns, hand sprayers, and boom systems where pressure control matters. Whether you’re spot-treating weeds around fence lines, applying herbicide on the boom, or mixing tank applications, consistent pressure means better coverage and less chemical waste.

Made to Last

TeeJet builds these cap assemblies to handle the harsh conditions you’ll find on the farm. The materials resist chemical corrosion and UV damage, while the pressure relief mechanism stays responsive even after thousands of cycles. This is the same quality construction that’s made TeeJet the go-to choice for agricultural spray equipment.

Good to Know

Installation takes just a few minutes—thread it on like any other cap and you’re ready to spray. The 20 PSI setting works well for most herbicide and pesticide applications where you need controlled pressure without overspray. If your existing cap doesn’t have pressure relief, you’ll appreciate having that safety net built right in.
