Anvil 0361530603 Black Lug Union 1 Inch Class 3000 Npt

Product Description

The ANVIL 0361530603 is a 1-inch black lug union designed for threaded pipe connections in high-pressure piping systems. Constructed from forged carbon steel with a black finish, this fitting meets Class 3000 requirements and carries a 3000 psi pressure rating. It uses NPT (National Pipe Taper) threads for a reliable, leak-resistant connection in both liquid and gas service applications. Plumbers, pipefitters, and mechanical contractors install this type of union where a break-apart connection point is needed without cutting or modifying the adjacent pipe run.

This lug union is suited for commercial and industrial piping installations where forged carbon steel fittings are specified. It is commonly installed on steam, gas, and liquid lines in mechanical rooms, boiler piping, and process piping where Class 3000 pressure ratings are required. The lug design allows the union to be tightened or broken loose using a wrench on the external lugs, making it practical in tight installation spaces.

Key Features

• Forged carbon steel construction for strength in high-pressure service
• Class 3000 rating with 3000 psi liquid and gas pressure rating
• 1-inch NPT threaded end connections
• Black finish for corrosion resistance in standard service environments
• Lug design allows wrench access in confined spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch NPT threaded piping systems rated to Class 3000 service, including steam, gas, and liquid applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Depressurize and isolate the piping system completely before disassembling or installing any union fitting. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly. Do not over-tighten; use the lug faces to achieve a wrench-tight connection without stressing the fitting body.
