Bk 161-104 3/4 in Mipt Sch 40 Compression Union Pvc Adapter

Product Description

The BK 161-104 is a 3/4-inch male iron pipe thread (MIPT) to compression union PVC adapter designed for cold water plumbing systems. One end features male pipe threads for direct connection to a threaded fitting or valve body, while the other end accepts compression-style tubing. Rated for Schedule 40 applications, this adapter bridges threaded pipe runs to compression fittings in a single component. Licensed plumbers and experienced DIYers use this fitting to transition between threaded and compression connections on cold water lines without soldering or solvent welding.

This adapter is suited for residential and light commercial cold water supply systems where a threaded-to-compression transition is required. It is compatible with Schedule 40 cold water iron pipe or PVC pipe, making it a practical choice during repairs, retrofits, or new rough-in work where mixed pipe materials or connection types are present at a single junction.

Key Features

• 3/4-inch MIPT thread on one end for direct connection to threaded fittings or valves
• Compression fit on opposite end eliminates the need for soldering or solvent cement
• Compatible with Schedule 40 cold water iron or PVC pipe
• Compact single-piece design simplifies threaded-to-compression transitions
• Lightweight at 0.207 pounds for easy handling in tight spaces

Compatibility

Designed to fit Schedule 40 cold water iron pipe or PVC pipe. Suitable as a threaded-to-compression transition adapter in cold water plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and fully depressurize the line before beginning work. Hand-tighten the MIPT connection first, then apply an appropriate thread sealant or PTFE tape before final tightening. Do not overtighten the compression nut, as this can crack PVC fittings or deform the compression sleeve.
