Anvil 0361500200 Black Union 1/8 Inch Threaded Class 3000

Product Description

The ANVIL 0361500200 is a forged carbon steel threaded union fitting with a black finish, rated for Class 3000 service. Sized at 0.125 inches (1/8 inch NPT), this union allows piping runs to be disconnected and reconnected without disturbing surrounding pipe sections. It conforms to ASME B1.20.1 thread standards and ASME B16.11 forged fittings specifications. The black finish provides a durable surface suitable for industrial and mechanical piping systems. Licensed plumbers, pipefitters, and HVAC technicians working on gas, steam, and liquid piping systems typically install this fitting. It weighs 0.38 pounds.

This union fitting is suited for residential and light commercial piping applications where a threaded makeup point is required in small-diameter pipe runs. Common installations include gas distribution lines, compressed air systems, steam lines, and hydronic heating piping where maintenance access or future serviceability is a design consideration. The small 1/8 inch size makes it appropriate for instrumentation takeoffs, low-flow branch connections, and pilot-line applications where Class 3000 pressure integrity is required.

Key Features

• 1/8 inch NPT threaded end connections conforming to ASME B1.20.1
• Meets ASME B16.11, ASTM A105, ASTM A182, and ASTM A350 material and dimensional standards
• Black finish for corrosion-resistant appearance in exposed or semi-exposed installations
• Three-piece union design allows pipe disassembly without cutting or unthreading adjacent sections
• Liquid and gas pressure rating of 3000 psi

Compatibility

Designed as an OEM-style threaded union fitting for use in Class 3000 forged carbon steel piping systems with 1/8 inch NPT threaded connections, conforming to ASME B16.11 forged fitting standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code or International Plumbing Code. Shut off and depressurize the piping system completely before disassembly or installation. Apply appropriate thread sealant or PTFE tape to NPT threads per the sealant manufacturer and local code requirements. Do not over-tighten the union nut, as forged fittings rely on the ground joint seat for sealing integrity.
