Description
Anyone who’s worked with spray equipment knows how frustrating it is when dirt, debris, or moisture gets into your system through open fittings. Whether you’re spot-treating weeds around the barn or spraying the garden for pests, keeping your female couplers protected between uses prevents contamination and keeps your sprayer running smooth. This 3/4-inch poly dust plug seals up those open connections tight, so you’re ready to spray when the job calls for it.
What You’re Getting
- Tight-fitting plug that keeps dirt, dust, and moisture out of your female cam lock couplers
- Lightweight poly construction that won’t crack or break if you drop it
- Easy to install and remove—just push in and twist to secure
- Bright color makes it easy to spot and remember to remove before connecting
- Won’t corrode or rust like metal plugs, even in harsh chemical environments
Built for Real Farm Work
This plug is designed for 3/4-inch cam lock systems commonly found on field sprayers, tank mixers, and chemical transfer equipment. The high-density polyethylene tank includes UV inhibitors so it won’t get brittle or crack from sitting in the sun. Solo builds their sprayers to handle the chemicals and conditions that come with farm work, and this plug follows the same approach—built to last through seasons of exposure to chemicals, weather, and hard use.
Made to Last
The poly material stands up to agricultural chemicals without degrading, and it won’t swell or shrink with temperature changes like some rubber plugs do. You can leave these plugs in place through winter storage or summer heat without worrying about them getting stuck or damaged.
Installation Notes
Just push the plug into the female coupler opening and give it a quarter turn to lock it in place. The cam design holds it secure but still allows for easy removal when you need to make connections. Keep a few extras on hand—they’re small enough to lose but cheap enough to replace.
