Product Description
The VIEGA 46333 is a zero-lead brass crimp adapter designed for use in PureFlow PEX piping systems. It transitions a 1/2-inch PEX crimp connection to a 1/2-inch female pipe thread (FPT) fitting, making it a standard transition component when connecting PEX tubing to threaded fixtures, valves, or equipment. At 1.37 inches in height and weighing just 0.09 pounds, it is compact and easy to handle in tight spaces. The zero-lead brass construction meets potable water requirements, and the part is manufactured in the USA. Licensed plumbers install this fitting in both rough-in and finish plumbing work across residential and light commercial applications.
This adapter is used wherever a PEX crimp run must terminate at a threaded connection point — such as at shutoff valves, fixture supply ports, water heaters, or manifold connections. The 1/2-inch size is the most common diameter in residential water distribution systems. It is compatible with standard 1/2-inch PEX crimp rings and the PureFlow crimp tool system. The FPT end accepts standard NPT male-threaded fittings.

Installation Notes
Installation is performed by a licensed plumber. Shut off the water supply and depressurize the line before installing. Use a calibrated PEX crimp tool to seat the crimp ring properly over the PEX tubing and fitting tail — do not over-crimp or under-crimp. Apply thread sealant or PTFE tape to the male NPT fitting before threading into the FPT end; hand-tighten first, then wrench-tighten to avoid cracking the fitting. Follow local plumbing codes and IPC guidelines for potable water piping.
