The Qimao Metal Manufacturer Step Bushing for Electrical And Plumbing Conduits Reducer Bushing lets you connect a smaller conduit or pipe into a larger fitting. Instead of changing the whole box or adapter, you just thread this bushing in and keep working. Electricians use them when they run EMT or rigid conduit into an enclosure that has a bigger hub. Plumbers use them too — when stepping down from a larger threaded pipe to a smaller one. This one works for both trades. No need to stock two different parts. The outside threads go into the larger female fitting. The inside threads accept the smaller male pipe or conduit. We make these in zinc-plated steel, so they don't rust out fast in damp basements or outdoor boxes. One part, one wrench, and you are done with the step-down.

Instead of handling a separate nut and cup washer, you get one ready-to-use part. The hex nut is spot welded right inside the cup washer, so it won’t slip or spin during tightening. This is a small change that saves real time when you’re putting together brackets, panels, or frames. The cup shape also helps the washer sit flush in countersunk or uneven surfaces. No more dropped nuts or misaligned washers. Just grab, position, and fasten. We make these in mild steel, stainless, or zinc-coated finishes depending on your job. From door hinges on trucks to mounting brackets on factory equipment, this little part quietly solves a big headache.
