Hex Bushing 1 in x 3/4 in Class 150
The Anvil 0318906641 is a malleable iron hex bushing designed to connect a 1 inch female NPT thread to a 3/4 inch male NPT thread. It is intended for plumbing professionals and maintenance technicians who need a reliable reducer in drain or piping systems. The fitting meets ASME B16.3 dimensional standards and carries UL and FM approvals for code compliance.
Pressure rated 300 psi at 150 degrees F
Malleable iron construction provides mechanical strength for saturated steam service up to 150 psi at 350 degrees F. The material remains stable across a temperature range of -20 degrees to 350 degrees F, making it suitable for hot water, steam and cold fluid lines. No moving parts or seals mean silent operation and no power draw.
FNPT x MNPT connection ready to install
The tapered pipe threads create a metal to metal seal when assembled with appropriate thread sealant. No gaskets, cartridges or electronic components are included or required. The hex profile allows standard wrench engagement for straightforward installation in new work or repairs.

Questions about this item
How do I install the 1 in x 3/4 in hex bushing with FNPT x MNPT threads?
Apply PTFE tape or pipe sealant to the MNPT male threads, then thread into the FNPT female port using a wrench on the hex flats; avoid over-tightening to prevent cracking the malleable iron.
Will the malleable iron bushing need replacement due to corrosion or wear?
Malleable iron resists deformation under pressure; inspect periodically for rust or thread damage, especially in steam service, and replace if leaks appear at the joint.
What pressure or temperature limit will be reached first during sustained steam use?
The saturated steam rating of 150 psi at 350 Degrees F is the first limit encountered; sustained operation above this pressure or temperature exceeds the Class 150 design.
