Step Bushing for Electrical And Plumbing Conduits Reducer Bushing

This Step Bushing for Electrical And Plumbing Conduits Reducer Bushing from Qimao Metal Manufacturer is a threaded reducer. Plain and simple. The outside has male threads that match a standard hub or female fitting. The inside has female threads that match your smaller conduit or pipe. You screw the bushing into the larger opening first, then thread your smaller pipe into the bushing. That is it. We see these used every day on electrical junction boxes, pull elbows, conduit bodies, and water pipe adapters. The zinc plating is not just for looks. It passes the salt spray test for indoor and outdoor use. The threads are clean cut, not rolled, so they grab well without galling. We check each batch with a go/no-go gauge. If the thread is off even a little, it does not leave the shop. Available from 1/2" to 4" in standard NPT or metric thread patterns.

Product Parameter (Specification)

Product Feature 

1. No thread – The step bushing outside no threads only a groove. The inside accepts a smaller pipe. One bushing does the whole step-down without extra adapters.

2. Zinc-plated steel body – Resists rust in wet locations like outdoor electrical boxes or basement plumbing. Much longer life than plain steel or aluminum.

3. Clean cut threads – We use sharp dies and change them often. No burrs, no rough spots. Threads start easy by hand and tighten without binding.

4. Works for both electrical and plumbing – Rated for EMT, rigid conduit, and standard threaded pipe. Stock one part instead of two separate SKUs.

5. Compact profile – Adds very little length to your fitting stack. Fits inside tight junction boxes where a full coupling would not clear the cover.

Application

1-Electrical junction boxes – If you use the Step Bushing for Electrical And Plumbing Conduits Reducer Bushing you have a 1" knockout on the box but only 1/2" conduit running to it. A step bushing fills the gap without changing the whole box.

2-Conduit bodies and LB fittings – Sometimes the factory hub is larger than your conduit run. Step bushings reduce the opening so your conduit threads in cleanly.

3-Plumbing pipe transitions – Adapting from a larger iron pipe to a smaller brass or steel nipple. The step bushing gives you a clean shoulder for the smaller pipe to seat against.

4-Outdoor lighting posts – Base posts often have 2" threaded hubs. The fixture wiring comes through 1/2" or 3/4" conduit. Step bushings make the connection weather-tight.

5-HVAC equipment connections – Condensate drains, refrigerant lines, and gas piping sometimes need thread reductions in tight spaces. The compact step bushing fits where a full coupling will not.

Usage Guide

Step 1 – Check your thread types Make sure both the groove of Step Bushing for Electrical And Plumbing Conduits Reducer Bushing and the smaller pipe use the same thread standard (NPT, BSP, or metric). Mixed standards will leak or cross-thread.

Step 2 – Clean both threads Remove old tape, dirt, or rust from the female hub and the male pipe end. Dry fit first without sealant to make sure threads start easily.

Step 3 – Apply sealant to the outer threads Use PTFE tape or pipe dope on the male threads of the step bushing. This seals the connection between the bushing and the larger hub.

Step 4 – Screw the bushing into the larger hub Turn clockwise until snug. Do not over-torque. Steel into steel can bind if you go too far.

Step 5 – Apply sealant to the inner threads Now put tape or dope on the smaller pipe's male threads.

Step 6 – Thread the smaller pipe into the bushing Again, hand tight plus one to two turns with a wrench. Do not use the bushing to lever against the larger hub.
