Viega 46032 Pex Brass Lav Insert Adapter Crimp Compression

Product Description

The VIEGA 46032 is a precision-machined, lead-free brass insert adapter designed to transition 3/8 inch PEX tubing to a 1/4 inch compression (CTS) connection. Used in potable water supply lines, this fitting is commonly installed at lavatory faucet supply stops where a PEX rough-in meets a compression-style fixture connection. The crimp-style PEX end requires a standard PEX crimping tool and an appropriately sized copper or stainless crimp ring. Its lead-free brass construction meets requirements for use in drinking water systems in both residential and commercial applications.

This adapter is suited for residential and commercial plumbing installations where PEX distribution lines terminate at lavatory faucets or similar fixtures with 1/4 inch compression inlets. It is typically installed by licensed plumbers during rough-in or fixture trim-out phases. The 3/8 inch crimp end connects directly to 3/8 inch PEX tubing, while the 1/4 inch compression end accepts standard compression fittings at the faucet supply inlet.

Compatibility

Designed as an OEM-style replacement fitting for potable water plumbing systems using 3/8 inch PEX tubing terminating at a 1/4 inch compression lavatory supply connection.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve line pressure before beginning work. The crimp end requires a calibrated PEX crimping tool and the correct-size crimp ring — do not substitute clamp rings without confirming compatibility with the fitting style. Hand-tighten the compression fitting before applying a final quarter-turn with a wrench to avoid overtightening and deforming the compression seat.
