Description

Whether you’re setting up a spray tank, closing off a drain port, or capping a line for the season, having the right plug makes all the difference. This 1-1/4 inch MNPT poly plug seals tight and keeps things where they belong—no more drips under the sprayer or contamination getting into your system when it’s parked.

What You’re Getting

Durable polypropylene construction that won’t crack or corrode like metal plugs
Standard 1-1/4 inch male pipe thread that screws right into your existing fittings
Chemical resistant material that handles fertilizers, herbicides, and other ag chemicals
Secure seal that won’t back out from vibration or pressure changes
Easy installation with just a wrench—no special tools needed

Built for Real Farm Work

This plug works great in spray tanks, nurse tanks, and liquid fertilizer systems where you need to seal off unused ports or temporarily cap lines. Banjo makes reliable agricultural fluid handling equipment, and this plug is built to the same standards as their pumps and fittings.

Made to Last

Polypropylene holds up to temperature swings, UV exposure, and the chemical cocktails that come with modern farming. Unlike metal plugs that can rust or seize, this poly plug threads in and out smoothly season after season. The material stays flexible enough to maintain a good seal without getting brittle over time.

Good to Know

A little pipe dope or Teflon tape on the threads ensures a leak-free seal and makes removal easier down the road. Don’t overtighten—the poly threads can strip if you get too aggressive with the wrench. Hand tight plus a quarter turn with a wrench is usually plenty to get a good seal without overdoing it.
