The NIBCO INC 9099455PCU is a lead-free press tee fitting designed to create a branch connection in a continuous pipeline without soldering or open flame. Sized at 1 inch by 1 inch by 3/4 inch, this tee allows a main run to continue straight through while routing flow to a perpendicular branch outlet. Press-style installation uses a dedicated press tool to mechanically crimp the fitting onto compatible pipe, producing a permanent, leak-tight joint. Licensed plumbers and pipefitters install this fitting in potable water, hydronic heating, and general plumbing distribution systems where flame-free methods are required or preferred.
This press tee is suited for residential and light commercial plumbing applications where a reducing branch connection is needed. The 1-inch-by-1-inch run with a 3/4-inch branch outlet accommodates common domestic water distribution configurations, including drops to fixtures or zone supply lines in hydronic systems. Its lead-free construction makes it appropriate for use in potable water service lines subject to safe-drinking-water regulations.
Designed as an OEM-style press fitting replacement for standard residential and commercial press-fit copper piping systems. Verify compatibility with the press tool jaw set required for the specific press-connection system in use.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and depressurize the supply line and drain the pipe section before cutting in the fitting. A manufacturer-approved press tool with the correct jaw size must be used to achieve a proper mechanical crimp. Do not use this fitting with pipe that is wet or under pressure during the press cycle, as an incomplete joint may result.
