Viega 90561 Pex Press Male Adapter 1 Inch Zero Lead Bronze

Product Description

The VIEGA 90561 is a zero-lead bronze PEX press male adapter designed to transition from a 1-inch PEX press connection to a 1-inch male pipe thread. The adapter ships with an attached press sleeve, allowing the installer to make a secure, tool-pressed joint without sourcing a separate sleeve. Manufactured from lead-free bronze, it meets drinking water and potable plumbing material requirements. This fitting is part of the VIEGA PureFlow Press system, model 2811ZL, and is suited for residential and light commercial hydronic heating and plumbing distribution piping. Licensed plumbers and pipefitters install this type of fitting as part of PEX-based rough-in work.

The 90561 is used in hydronic heating systems and general plumbing applications where PEX tubing transitions to threaded iron pipe size connections. The 1-inch PEX press end accepts standard 1-inch PEX tubing, while the male NPT end connects to valves, manifolds, boiler supply or return ports, and other threaded components. Its zero-lead bronze construction makes it appropriate for both heating loops and cold or hot potable water distribution where lead-free fittings are required by code.

Installation Notes

Installation requires a VIEGA-compatible PEX press tool with the correct jaw size for 1-inch fittings. Shut off water supply and depressurize the line before making any connections. The threaded male end should be sealed with PTFE tape or an approved pipe thread sealant and tightened per standard plumbing practice — do not overtighten bronze threaded fittings. Work must comply with applicable local plumbing codes and the International Plumbing Code (IPC) where adopted.
