Sharkbite/cash Acme UC444LFA Brass Barb Pex Tee 3/4x1/2x3/4

Product Description

The SHARKBITE/CASH ACME UC444LFA is a lead-free brass barb PEX tee fitting sized 3/4 inch x 1/2 inch x 3/4 inch, designed for use in residential and light commercial potable water distribution systems. It connects PEX tubing using stainless steel cinch clamps applied with a cinch tool, providing a secure, corrosion-resistant joint. The brass construction delivers durability in both hot and cold water service, and the wetted surfaces contain less than 0.25% lead by weight, meeting the requirements of California AB1953 and Vermont VT S152 low-lead statutes. This fitting is installed by licensed plumbers during rough-in or retrofit work on PEX-based water supply lines.

The UC444LFA is suited for potable water supply systems using SDR-9 dimensional standard PEX tubing. It is NSF 61 listed for use in potable water systems and NSF CL-R certified for hot water applications where chlorinated water at up to 140 degrees F is continuously recirculated. The fitting conforms to ASTM F-876, ASTM F-877, and CSA B137.5 standards. Typical installations include branch takeoffs in residential water distribution manifolds or point-of-use supply connections where a 3/4 inch main run feeds a 1/2 inch branch outlet.
