Description

When you need to cap off a fitting or seal up a tank port for the season, having the right plug on hand saves you from making an extra trip to town. This 1-1/4 inch MNPT poly plug threads right into female NPT fittings and gives you a tight seal that won’t leak or let in debris. It’s one of those simple parts that proves its worth when you need it most.

What You’re Getting

Threaded male NPT design that screws in securely and seals properly
Chemical-resistant poly construction that stands up to fertilizers, herbicides, and cleaning solutions
Standard 1-1/4 inch size fits common tank ports and equipment fittings
Lightweight but durable—won’t crack or break when you tighten it down

Built for Real Farm Work

This plug is sized for the larger fittings you’ll find on spray tanks, nurse tanks, and bulk storage systems. Whether you’re winterizing equipment, blocking off unused ports, or need a temporary seal while working on plumbing, it handles the job without fuss.

Made to Last

The poly material resists the chemicals you use every day on the farm and won’t corrode like metal plugs can. It stays flexible through temperature changes and maintains a good seal even after sitting for months in storage.

Good to Know

Thread these in snug but don’t overtighten—the poly material seals well without needing excessive force. A little pipe thread compound helps ensure a watertight fit if you’re dealing with pressure or liquid storage applications.
