Nibco 9031200PC Copper Press X Mnpt Adapter 3/4x1/2

Product Description

The NIBCO 9031200PC is a wrot copper adapter fitting designed to transition between a press-connect end and a male NPT threaded connection. It measures 3/4 inch on the press end and 1/2 inch on the MNPT end, making it a compact reducing adapter for copper press systems. This fitting is domestically manufactured and is installed by licensed plumbers and pipefitters working on commercial and residential water supply and hydronic systems. The press-connect end eliminates open-flame soldering at the joint, reducing fire risk and speeding up installation in tight or sensitive spaces.

This adapter fits into copper press piping systems where a transition to a male threaded component is required — such as a valve, sensor, gauge, or threaded nipple. The 3/4 inch press inlet accommodates standard copper tubing, while the 1/2 inch MNPT outlet threads directly into female-threaded equipment ports. It is well suited for mechanical rooms, equipment connections, and retrofit work where press tooling is already on site.

Key Features

• Press x MNPT end configuration allows direct connection between copper press pipe and threaded equipment
• Reducing adapter steps down from 3/4 inch press to 1/2 inch male NPT
• Wrot copper construction provides corrosion resistance and durability in potable water and hydronic applications
• No-flame press connection reduces installation time and eliminates hot-work permits at the press end
• Domestically manufactured

Compatibility

Designed as an OEM-style fitting for use in copper press piping systems with 3/4 inch press tubing and 1/2 inch female NPT-threaded components such as valves, gauges, or equipment ports.

Installation Notes

Installation of this fitting should be performed by a licensed plumber in accordance with applicable local plumbing codes and ASME B16.18 standards. Shut off and depressurize the water supply before beginning work. The press end requires a compatible press tool and jaw set rated for copper press fittings — verify jaw compatibility with the fitting size before pressing. The MNPT end should be assembled with an appropriate thread sealant or tape rated for the service fluid and pressure.
