Macomb Group Approved 50050040080CSRTI Reducing Tee Xs Sch 80

Product Description

The MACOMB GROUP APPROVED 50050040080CSRTI is a welded carbon steel reducing tee designed for high-pressure piping systems where a branch reduction is required. Nominal size is 5 x 5 x 4 inches with an Extra Strong (XS) Schedule 80 wall designation. Outside diameters measure 5.56 x 5.56 x 4.5 inches, and center-to-end dimensions are 4.88 x 4.88 x 4.62 inches. This fitting meets NACE MR0175, NACE MR0103, and ISO 15156-2 standards, making it suitable for sour-service and corrosive-fluid environments. Licensed pipefitters and industrial piping contractors are the primary installers of this component.

This reducing tee is suited for industrial and commercial piping applications where a 5-inch run must branch to a 4-inch outlet. Its compliance with NACE MR0175, NACE MR0103, and ISO 15156-2 makes it appropriate for oil and gas, chemical processing, and other sour-service environments where hydrogen sulfide exposure is a concern. The welded construction and XS Schedule 80 rating support elevated pressure and temperature service conditions typical of these installations.
