Viega 90526 Press X Mnpt Adapter 1/2 X 3/4 Inch Bronze

Product Description

The VIEGA 90526 is a bronze press-to-male NPT transition adapter designed for use in PureFlow press-fit piping systems. It connects a 1/2-inch press-end fitting to a 3/4-inch male NPT threaded outlet, allowing plumbers to transition from a press-fit copper or PEX system into a standard threaded pipe connection. The bronze construction provides corrosion resistance and durability in both hot and cold potable water applications. Licensed plumbers install this fitting during new construction or retrofit work where press tooling is already on site.

This adapter is used in residential and light commercial plumbing systems where a press-fit line must terminate or connect into a threaded valve, manifold, or fixture supply. It is suited for installations in tight spaces where torch work is not permitted or preferred, such as occupied buildings, remodels, or code jurisdictions that restrict open-flame work near combustibles. The 1/2-inch press inlet and 3/4-inch MNPT outlet accommodate common size transitions found at water heaters, pressure reducing valves, and zone valves.

Key Features

• 1/2-inch press inlet transitions to 3/4-inch male NPT outlet for common size-step connections
• Bronze material offers corrosion resistance suitable for potable water service
• Press-fit end eliminates open-flame soldering, reducing fire risk and installation time
• Male NPT thread mates with standard threaded valves, fittings, and equipment ports
• Compact adapter profile fits in confined plumbing chases and mechanical rooms

Compatibility

Designed as an OEM-style press fitting for use within the VIEGA PureFlow press-fit piping system. Verify press jaw and tool compatibility with the 1/2-inch press end before installation.

Installation Notes

Installation should be performed by a licensed plumber familiar with press-fit tooling and NPT thread sealing practices. Shut off and depressurize the water supply and drain the line before pressing or threading any fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads per the fitting manufacturer and local plumbing code requirements. Do not use a press tool on a fitting that already has a completed press ring, and inspect the press indicator before making each connection.
