Anvil 361335201 3-inch FNPT x 1-1/2-inch MNPT Hex Bushing Coupling

Industrial Pipe Fitting

The Anvil 361335201 is a forged steel hex bushing that connects a 3-inch female NPT thread to a 1-1/2-inch male NPT thread. It is designed for installers who need a thick-walled reducer in chemical, petrochemical, pulp, paper, shipbuilding, waste incineration or semiconductor piping systems. The component provides a simple, economical way to transition between different pipe diameters. It must be paired with properly rated nipples and pipe for a secure assembly.

Sustained Pressure Performance

The thick-walled forged steel construction maintains structural integrity under continuous operating pressures found in industrial water and oil lines. Material strength resists deformation during prolonged exposure to process fluids in chemical or petrochemical service. The fitting remains dimensionally stable across the temperature cycles common in pulp, paper and semiconductor applications. It delivers reliable sealing without the fatigue that can affect thinner-walled alternatives over time.

Thermal and Installation Characteristics

Forged steel handles the thermal expansion and contraction of hot water, oil or steam service without cracking or leaking at the threads. The hex profile allows high torque application during make-up, creating a leak-tight joint that stays sealed through vibration and thermal cycling. No additional power or active cooling is required for the fitting itself. Correct thread engagement with rated pipe ensures safe operation in the listed industrial environments.
