Boshart SS304B73 304 Stainless Steel Reducing Bushing, ISO4144 Threaded

The Boshart SS304B73 is a threaded reducing bushing machined from 304 stainless steel and manufactured to the ISO4144 dimensional standard. This rough-in fitting family steps a larger threaded connection down to a smaller threaded outlet, and is available in reducing sizes from 1-1/4" x 1" up to 1-1/2" x 1", giving contractors and plumbers a corrosion-resistant option for stainless steel threaded pipe systems where a standard galvanized or brass bushing is not suitable. Because every size in this family is built to ISO4144, each bushing is dimensionally compatible with standard stainless steel threaded fitting systems used in potable water, process, and general piping installations calling for stainless construction. Boshart supplies this bushing packaged 30 pieces to the case across the size range, making it a practical stock item for shops and supply houses that move volume on stainless threaded fittings.
