Charlotte Pipe 3848 Pvc Plug 1 in Mnpt Sch 40 150 Psi

Product Description

The CHARLOTTE PIPE 3848 is a Schedule 40 PVC male pipe plug with a 1-inch nominal MNPT end style. It is used to cap or block threaded pipe openings in pressurized liquid distribution systems. Rated to 150 psi and 140 degrees F, this plug handles typical working pressures found in residential and light commercial plumbing lines. The white PVC construction resists corrosion and chemical attack from common plumbing fluids. Plumbers and pipefitters install this fitting when decommissioning a branch line, capping a test port, or completing a rough-in before fixture installation.

This plug is suited for pressurized liquid distribution in Schedule 40 PVC piping systems. It is intended for use with water distribution lines, irrigation headers, and similar low-to-moderate pressure plumbing applications. It is not rated for gas service or compressed air beyond its stated pressure limit. The MNPT thread mates directly with female-threaded PVC fittings, valves, and tees. Domestic manufacture supports consistent thread tolerance and material quality across production runs.

Compatibility

Designed as an OEM-style replacement fitting for Schedule 40 PVC pressurized liquid distribution piping systems with 1-inch nominal female NPT threaded connections. Intended for distribution of pressurized liquids only.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following local plumbing codes and IPC guidelines. Shut off and depressurize the line before threading in the plug. Apply an appropriate thread sealant or PTFE tape to the male threads before hand-tightening and finishing with a strap wrench — do not over-torque PVC threads, as this can crack the fitting. Pressure-test the assembly after installation to confirm a leak-free seal before returning the system to service.
