The ANVIL INTERNATIONAL INC 8700159208 is a 3/8-inch black pipe plug designed to seal threaded pipe openings in piping systems. This fitting is used to cap off unused ports, branch outlets, or test points in low- to medium-pressure pipe assemblies. Sold in a package of 100 units, it suits contractors and supply houses stocking for recurring installation and maintenance work. The black finish indicates a standard carbon steel or black-iron construction typical of this plug style, making it appropriate for use in gas, air, water, and similar compatible service lines where the finish is acceptable per applicable codes.
Black pipe plugs of this type are commonly installed in residential and light commercial plumbing, HVAC, and gas piping systems. Typical applications include capping test ports after pressure testing, sealing unused tee outlets, and blanking off manifold ports during system commissioning or modification. Plumbers, pipefitters, and HVAC mechanics regularly stock this plug size due to its frequency of use across both new construction and retrofit work.
Designed as an OEM-style threaded pipe plug for use with standard 3/8-inch NPT threaded pipe fittings and pipe systems.
Installation is performed by licensed plumbers, pipefitters, or HVAC technicians depending on the service application. Always depressurize and isolate the piping system before installing or removing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads per the system service requirements and local code. Verify that the plug material and finish are compatible with the intended service fluid or gas before installation.
