Zoro Select 1" MNPT x 3/8" FNPT Bushing

This galvanised hex bushing connects a one-inch male NPT thread to a three-eighths-inch female NPT thread. It is manufactured from malleable iron with a Class 150 pressure rating for general plumbing installations. The fitting is supplied new and carries a California Proposition 65 warning regarding chemicals known to cause cancer and reproductive harm.

Build Integration And Clearance

The hex profile allows tightening with a standard wrench without damaging the fitting body. Its straight-thread design requires compatible NPT counterparts and thread sealant to achieve a leak-free joint. The reducer configuration frees up space by stepping down pipe size directly at the connection point rather than using a separate coupling and nipple assembly.

Target Installers And Limitations

This bushing suits plumbers and maintenance crews reducing a one-inch line to a three-eighths-inch branch in water, air or inert gas systems rated for Class 150 service. It is not intended for applications exceeding that pressure class, for potable water systems requiring lead-free certification, or for installers who need a stainless steel or brass fitting for corrosion resistance.
