The ANVIL INTERNATIONAL INC 8700159802 is a 3/8 inch galvanized pipe plug used to seal threaded pipe openings in plumbing, HVAC, and piping systems. The galvanized finish provides corrosion resistance for use in standard service environments. This plug is a small but critical fitting used to cap off unused branch connections, test ports, or threaded outlets. Plumbers and pipefitters install these during rough-in, system modifications, and pressure testing. The 3/8 inch size fits standard NPT threaded fittings of that size class.
This plug is suited for residential and light commercial piping installations where a threaded closure is needed on a 3/8 inch port. Common applications include capping unused tee outlets, sealing test ports after inspection, and closing off branch lines during phased construction or system modifications. It is a standard stock item for plumbers and mechanical contractors who regularly work with threaded pipe assemblies.
Designed as an OEM-style replacement and standard-stock fitting for threaded pipe systems using 3/8 inch NPT connections in plumbing and mechanical piping applications.
Installation is performed by licensed plumbers or qualified pipefitters. Shut off system pressure and drain the line before removing or installing threaded plugs. Apply appropriate thread sealant or PTFE tape to the threads before tightening. Do not overtighten, as this can crack the fitting or damage the mating threads.
