Nibco px80810a F1807 Pex Reducing Tee 1 X 3/4 Inch

Product Description

The NIBCO px80810a is a lead-free PEX reducing tee fitting manufactured to ASTM F1807 standards, used in potable water supply systems and hydronic distribution piping. The fitting joins a 1-inch main run to a 3/4-inch branch outlet using a crimp-style connection compatible with standard PEX crimp rings and tools. Its lead-free construction meets NSF 61 and Safe Drinking Water Act requirements, making it suitable for both hot and cold potable water applications. Licensed plumbers and pipefitters typically install this fitting in residential and light commercial systems during new construction or repipe work.

This fitting is designed for use in PEX crimp systems that follow the ASTM F1807 crimp ring specification. The 1-inch by 3/4-inch reducing configuration is a common size for branching off a trunk line to a secondary supply run or individual fixture branch. Typical applications include residential water distribution systems, manifold branch feeds, and in-floor radiant heating loops where flow reduction between main and branch lines is required.
