Anvil 0361175201 Black Reducing Coupling 3/8 X 1/4 in Npt

Product Description

The ANVIL 0361175201 is a black reducing coupling designed to connect threaded pipe runs where the line size steps down from 3/8 inch to 1/4 inch. Forged from carbon steel with a black finish, this fitting is rated to Class 3000 and carries a 3000 psi pressure rating, making it appropriate for demanding piping applications in gas and liquid service. The fitting uses NPT threads conforming to ASME B1.20.1 and is manufactured to ASME B16.11 dimensional standards. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers. It weighs 0.15 pounds and ships as a single piece.

This reducing coupling is suited for use in commercial and industrial piping systems where a transition from 3/8 inch to 1/4 inch pipe is required in threaded configurations. Common applications include compressed air, hydraulic, fuel gas, and process fluid lines. The Class 3000 rating means it handles higher-pressure service than standard malleable fittings, making it a frequent choice in mechanical rooms, equipment connections, and instrumentation piping where compact forged fittings are specified.

Key Features

• Forged carbon steel construction rated to Class 3000 for high-pressure service
• 3000 psi pressure rating suitable for gas and liquid service
• NPT threaded end connections conforming to ASME B1.20.1
• Manufactured to ASME B16.11 dimensional and ASTM A105, A182, and A350 material standards
• Black finish for corrosion resistance in standard service environments
• Compact reducing design transitions 3/8 inch to 1/4 inch in a single fitting

Compatibility

Designed as an OEM-style threaded reducing coupling for use with standard NPT-threaded 3/8 inch and 1/4 inch pipe in Class 3000 forged steel piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the International Fuel Gas Code (IFGC) and International Plumbing Code (IPC) where gas or fluid service is involved. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before assembly. Do not over-tighten forged fittings, as excess force can damage threads or crack the fitting body.
