The ANVIL INTERNATIONAL INC 8700158556 is a 1/4 inch galvanized merchant coupling designed for joining threaded pipe sections end to end in piping systems. Merchant couplings are full-length couplings threaded throughout their interior, accepting male-threaded pipe on both ends. The galvanized steel construction provides corrosion resistance for use in water supply, light industrial, and general plumbing applications. Licensed plumbers and pipefitters install this fitting as a standard connection component in low-pressure piping assemblies. At 1/4 inch, it fits small-diameter pipe runs where a secure, leak-resistant threaded joint is required.
This coupling is suited for residential and light commercial plumbing installations, including domestic water supply lines, compressed air distribution, and general-purpose pipe assemblies. It is commonly used wherever two threaded pipe ends must be joined inline without a union. The steel-threaded, end-to-end design ensures full thread engagement for a tight, reliable connection. This item is sold in a package quantity of 100 units, making it appropriate for contractors stocking fittings for ongoing installation work.
Designed as an OEM-style replacement and standard fitting for 1/4 inch NPT threaded pipe systems in residential and light commercial plumbing applications.
Installation is performed by a licensed plumber or qualified pipefitter using standard pipe wrenches and thread sealant or PTFE tape applied to male threads. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Thread engagement should be checked for full seating without cross-threading. Follow applicable IPC and local plumbing code requirements for fitting selection in pressurized systems.
