PVC 439-251 Fitting Reducer Bushing 2" MIPT x 1 1/2" FIPT

This PVC reducer bushing provides a threaded transition between a larger male pipe thread and a smaller female pipe thread. It is intended for common plumbing irrigation and pool and spa applications where a durable corrosion resistant PVC threaded adapter is required. The design works with standard threaded pipe fittings and offers a compact way to adapt pipe sizes without cutting pipe.

• Material and construction: PVC material for corrosion resistance and long service life
• Thread types: MIPT male iron pipe thread at the larger end and FIPT female iron pipe thread at the smaller end
• Typical compatibility: standard Schedule 40 PVC threaded fittings and common NPT based pipe systems
• Common uses: plumbing irrigation pool and spa service, water handling, and general threaded transitions

Product specifications

• Nominal connection sizes: 2 inch MIPT to 1 1 2 inch FIPT
