Description
You know that feeling when you’re halfway through spraying a field and start wondering if one section of your boom might not be flowing right? With chemical costs what they are, you can’t afford to miss spots or waste product on double applications. This green polypropylene flow indicator ball gives you instant visual confirmation that liquid is moving through your Wilger flow monitor system.
What You’re Getting
- Bright green color that’s easy to spot from the cab or when walking the boom
- Made from durable polypropylene that won’t break down from chemical exposure
- Lightweight design that responds to even low flow rates
- Direct replacement part that fits all Wilger modular flow monitor systems
Built for Real Farm Work
This indicator ball works in boom sprayers of all sizes, from small pull-behind units up to big self-propelled machines. Whether you’re applying herbicide in the spring, fungicide during growing season, or liquid fertilizer, you’ll see at a glance if each section is getting proper flow.
Made to Last
Farm chemicals are tough on plastic parts, but polypropylene holds up better than most materials. This ball won’t crack, fade, or get brittle after seasons of exposure to herbicides, insecticides, and fertilizers. The bright green color stays visible even after years of use.
Good to Know
Installation is simple—just drop the new ball into your flow monitor housing when you’re doing routine maintenance. If your old ball gets stuck or discolored, it’s time for a replacement. Keep a few spares on hand since they’re small and easy to lose during boom service.
