A faulty trigger assembly can waste chemical, create uneven application, and turn what should be precision work into a frustrating mess. This trigger assembly gets your BPS42 sprayer back to working the way it should.
What You’re Getting
- Complete trigger assembly that’s ready to install out of the box
- Smooth, responsive trigger action that gives you precise control over spray flow
- Positive shut-off that stops drips and prevents waste of expensive chemicals
- Durable construction built to handle the chemicals and conditions you work with
- Direct replacement design that fits your BPS42 sprayer perfectly
Built for Real Farm Work
This trigger assembly is designed specifically for BPS42 sprayers, which are commonly used for spot spraying weeds, applying herbicides around fence lines, treating problem areas in pastures, and general chemical application work around the farm. Whether you’re hitting thistle patches, treating brush along ditches, or doing precision weed control in crop fields, having a reliable trigger makes all the difference.
Made to Last
Farm sprayers take abuse—they get bounced around on ATVs, exposed to harsh chemicals, and used in dusty, dirty conditions. This trigger assembly is built with materials that resist chemical corrosion and maintain their seal even after thousands of cycles of use.
Installation Notes
Installation is straightforward—just remove the old trigger assembly and thread in the new one. Make sure to check the connection points for any chemical buildup before installing, and consider replacing any worn seals or gaskets while you’ve got things apart.
