Description
When you’re connecting pipes or extending tank fittings on your sprayer, you need a reliable nipple that won’t crack under pressure or degrade when exposed to chemicals. This 3-inch MNPT poly nipple gives you a solid connection that handles the demands of agricultural applications while resisting the corrosive effects of fertilizers and herbicides.
What You’re Getting
- Durable polypropylene construction that resists chemical corrosion and won’t rust like steel fittings
- Male pipe threads on both ends for secure connections to tanks, valves, and other fittings
- Heavy-duty design that handles the pressure and vibration of field spraying operations
- Chemical resistance that stands up to most agricultural chemicals without degrading or weakening
Built for Real Farm Work
This nipple is perfect for spray tank systems, nurse tanks, and chemical mixing setups where you need to connect different components or extend existing fittings. It’s commonly used in tank plumbing for crop sprayers, liquid fertilizer applicators, and chemical transfer systems where reliability matters.
Made to Last
Unlike metal fittings that rust and corrode over time, this poly construction keeps working season after season. The polypropylene material won’t break down when exposed to most agricultural chemicals, and it handles temperature swings without cracking or becoming brittle.
Installation Notes
Thread this fitting in hand-tight plus a quarter turn with pipe wrenches—don’t over-tighten poly fittings as they can crack. Use pipe thread compound or Teflon tape on the threads for a leak-free seal. Check connections periodically during the season to ensure they stay tight.
