Anvil 0308002005 Threaded Pipe Flange 3/4 in Class 125

Product Description

The ANVIL 0308002005 is a threaded pipe flange designed for use in low-pressure piping systems where a secure, removable pipe connection is required. Cast iron construction and a Class 125 pressure rating make this flange suitable for water, steam, and general service applications. The flange accepts 3/4 inch threaded pipe, measures 3-7/8 inches in outside diameter, and features a 5/8 inch hub length. Four bolt holes are positioned at 1-3/4 inches across bolt hole centers, with each bolt hole measuring 3/4 inch. Rated to 175 psi, it conforms to ASME B16.1 standards. Licensed plumbers and pipefitters are the typical installers for this type of hardware.

This flange is suited for residential and commercial piping applications where 3/4 inch threaded connections are required at terminal points, equipment connections, or branch takeoffs. It is commonly installed at pump housings, boiler connections, and general mechanical room piping. The ASME B16.1 Class 125 rating places it in standard low-pressure service categories used throughout hydronic heating, cooling, and potable or process water systems.
