Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Meet the Smith-Cooper 1-1/2 in. MIP Stainless Steel Square Head Plug, a robust, lead-free solution designed to seal pipe ends with precision and reliability. Built from stainless steel, this plug delivers enduring performance in a variety of plumbing and industrial environments, while its square head makes installation and removal effortless in tight spaces.

Key benefits at a glance:

  • Size and connection: 1-1/2" nominal diameter with MIP (male iron pipe) threads, designed to thread into standard 1-1/2" female fittings for a secure seal.
  • Materials you can trust: Stainless steel construction provides excellent corrosion resistance and longevity, even in challenging applications.
  • Safety and compliance: Lead-free composition for safer plumbing and maintenance work.
  • Pressure rating: Rated up to 300 psi, making it suitable for a wide range of service pressures in water, air, and non-corrosive fluids.
  • Designed for easy service: A square head allows solid grip with a wrench or pliers, enabling quick tightening or removal in constrained spaces.
  • Packaging: Bagged packaging keeps the plug clean and ready for installation or storage.

Use cases and practical applications:

  • Sealing unused ports or service lines during maintenance, testing, or seasonal shutoffs.
  • Temporary or permanent end caps on plumbing runs in both residential and commercial settings.
  • Durable sealing solution for equipment housings, piping manifolds, or other stainless steel systems where a reliable MIP plug is required.

Installation tips for best results:

  • Clean threads before installation to ensure a reliable seal and easy removal later.
  • Choose a compatible thread sealant or PTFE tape suitable for stainless steel and the fluid being conveyed; apply in the direction of tightening to prevent unraveling.
  • Hand-tighten first, then snug with a wrench to achieve the proper seal without over-torquing.

Designed for professionals and DIYers who demand durability, safety, and straightforward service, the Smith-Cooper 1-1/2 in. MIP Stainless Steel Square Head Plug is a dependable choice for leak-free performance up to 300 psi. When you need a reliable, lead-free plug that installs quickly and lasts, this is the plug you reach for.
