The ANVIL INTERNATIONAL INC 8700135307 is a galvanized reducing coupling designed to connect pipes of two different diameters in threaded piping systems. It transitions from a 3/4-inch female thread on one end to a 3/8-inch female thread on the other, allowing for a reduction in line size without additional fittings. The galvanized finish provides corrosion resistance suited for use in water supply, gas distribution, and general mechanical piping applications. Licensed plumbers and pipefitters typically install this fitting in residential and light commercial systems where steel threaded pipe is specified.
This reducing coupling is used in threaded steel pipe assemblies where a line size change is required. Common applications include water supply distribution, heating system piping, compressed air lines, and low-pressure gas piping. The fitting is sold in a package quantity of 50 units, making it a practical stocking item for plumbing contractors and supply houses handling repetitive rough-in work.
Designed as an OEM-style replacement fitting for standard NPT threaded steel pipe systems requiring a 3/4-inch to 3/8-inch reduction.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC code requirements. Shut off and depressurize the supply line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly. Do not overtighten, as this can crack fittings or damage threads.
