Parts Desk Insights
Best Use Case: Use this cored hex-head pipe plug to close off a 1/8" NPT threaded port and provide wrench access for future service.
Common Issues: Avoid cross-threading on NPT fittings; confirm thread size (1/8" NPT) and plug style (cored) match the mating port before install. Follow your system’s sealing method (e.g., compatible thread sealant/gasket approach) and ensure it is not used in potable water systems.
