When you’re setting up spray tanks, chemical tanks, or any plumbing system on the farm, you need reliable caps to seal off unused openings. This 3/4-inch FNPT poly cap does exactly that—keeping dirt, moisture, and debris out of your tank fittings while giving you a secure closure you can count on.
What You’re Getting
- Female NPT threads that screw right into male fittings for a tight seal
- Durable polypropylene construction that won’t crack or split under pressure
- Chemical-resistant material that stands up to fertilizers, herbicides, and other farm chemicals
- Standard 3/4-inch size fits most common tank fittings and plumbing setups
Built for Real Farm Work
This cap works perfectly on spray tanks, nurse tanks, fuel tanks, and water systems where you need to close off a 3/4-inch male NPT fitting. It’s the same type of cap that comes on tank fittings from manufacturers like Banjo, so you know it’ll do the job right.
Made to Last
Farm chemicals and weather can be tough on plastic parts, but this polypropylene cap is built to handle both. The material stays flexible in cold weather and won’t get brittle from UV exposure or chemical contact.
Installation Notes
Just hand-tighten it onto the male threads—no need for pipe dope or tape since the tapered NPT threads create their own seal. Keep a few extras in your toolbox since these small parts have a way of walking off when you need them most.
