Whether you’re setting up a new sprayer system or doing maintenance on tank fittings, sometimes you need to cap off a connection to keep things clean and secure. This 1-1/4 inch poly cap screws right into your female NPT threads and seals everything up tight, so you don’t have dirt, debris, or moisture getting where it shouldn’t be.
What You’re Getting
- Durable polypropylene construction that won’t crack or corrode like metal caps
- Standard 1-1/4 inch FNPT threading for a secure, leak-proof connection
- Chemical-resistant design that holds up to fertilizers, herbicides, and other ag chemicals
- Lightweight yet tough enough for farm equipment applications
Built for Real Farm Work
This cap fits any 1-1/4 inch female NPT connection you’ll find on sprayer tanks, nurse tanks, and other liquid handling equipment. It’s perfect for sealing unused tank outlets, protecting fittings during transport, or temporarily closing off lines while you’re working on other parts of the system.
Made to Last
Banjo builds these caps from high-quality polypropylene that won’t rust, corrode, or break down from UV exposure. The material stays flexible in cold weather and won’t get brittle from chemical exposure, so it keeps sealing properly season after season.
Good to Know
Hand-tightening is usually enough to get a good seal—don’t overtighten or you might crack the threads. A little pipe thread compound helps ensure a watertight connection if you’re dealing with pressure applications. Keep a few extras on hand since caps have a way of walking off when you need them most.
