About Product Overview

This hex bushing steps a 4-inch male pipe thread down to a 2-inch female thread, letting you connect mismatched black iron pipe sizes without swapping out your whole run. The malleable iron construction and black finish are built for black iron pipe systems, commonly used in gas and steam lines, and the hex shape gives you flat surfaces to grip with a wrench when torque calls for it.

  • End 1: 4" MIP (male iron pipe)
  • End 2: 2" FIP (female iron pipe)
  • Material: Malleable iron with black finish
  • Rated for up to 300 PSI and 150°F
  • Lead-free construction

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.
