Boshart SS304B Stainless Steel Threaded Reducing Bushing, ISO4144

Boshart SS304B Stainless Steel Threaded Reducing Bushing, ISO4144

The Boshart SS304B is a reducing bushing machined from 304 stainless steel and built to the ISO4144 threading standard, giving plumbers and contractors a corrosion-resistant fitting for stepping a larger threaded port down to a smaller connection on stainless steel piping systems. This bushing is available in a range of reducing sizes, including 1" x 3/4", 1/2" x 3/8", 2" x 1", 3/4" x 1/4", and 3/4" x 1/2", so installers can select the exact reduction needed for a given rough-in or process piping transition. Stainless steel construction makes this bushing well suited for rough-in and process applications where standard malleable iron or brass would be prone to corrosion. Each size ships as part of a 50-piece package, making it a practical choice for stocking trucks or supply houses that regularly install stainless steel threaded fittings.
