Viega 90541 Press X Fnpt Pipe Adapter 1/2 Inch

Product Description

The VIEGA 90541 is a 1/2 inch nominal press-by-female NPT pipe adapter designed to transition between press-fit copper tubing systems and standard female threaded pipe connections. Constructed from bronze, this adapter provides a durable, corrosion-resistant connection point in potable water, hydronic heating, and mechanical piping systems. The press end eliminates the need for open flame soldering, while the FNPT end accepts standard male-threaded fittings. Licensed plumbers and pipefitters install this fitting during new construction and retrofit work where mixed connection styles are required.

This adapter is suited for residential and light commercial plumbing and hydronic applications. It is commonly used where a press-fit copper line must transition to a threaded valve, sensor, gauge, or other threaded component. The 1/2 inch size fits standard half-inch copper tubing on the press side and 1/2 inch NPT male threads on the pipe side. It is appropriate for indoor mechanical rooms, utility spaces, and in-wall rough-in locations where a reliable, no-torch connection method is preferred.

Key Features

• Press x FNPT end style allows connection between press-fit copper systems and threaded pipe components without soldering
• Bronze construction offers corrosion resistance suitable for potable water and hydronic service
• 1/2 inch nominal size fits standard half-inch copper tubing and 1/2 inch NPT male threads
• No open flame required on the press end, reducing fire risk and improving installation speed

Compatibility

Designed as an OEM-style press-to-female-NPT transition fitting for use in 1/2 inch copper press piping systems where a threaded connection point is required.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and applicable IPC requirements. Shut off and depressurize the water supply before making any connections. The press end requires a compatible press tool and jaw set rated for the fitting size and manufacturer specification. Confirm the press end seal ring is properly seated before pressing, and verify the threaded connection is made up with appropriate thread sealant or tape per the fitting service requirements.
