Anvil International Inc 8700163150 Black Iron Union 1-1/2 in

Product Description

The ANVIL INTERNATIONAL INC 8700163150 is a 1-1/2 inch black malleable iron ground joint union with an inserted brass seat. It is designed for threaded pipe assemblies where a secure, removable connection is required in steam, water, oil, or gas piping systems. The ground joint design provides a metal-to-metal seal at the union face, and the brass seat insert ensures a reliable seating surface over repeated make-and-break cycles. Rated for working pressures up to 150 LB steam and 300 LB cold water, oil, or gas service. Licensed plumbers and pipefitters install this fitting in commercial and industrial mechanical rooms, boiler rooms, and process piping applications.

This union is suited for black iron pipe installations in both residential and commercial settings. Common applications include steam heating distribution lines, hydronic systems, natural gas branch piping, oil supply lines, and cold water service runs. The 1-1/2 inch size fits standard Schedule 40 black iron pipe of the same nominal diameter. It is sold in packages of 15 units, making it practical for contractors stocking multiple fittings for a project.
