The VALUE COLLECTION 4RSB2*11/2 is a threaded pipe reducer fitting designed to connect a 2-inch pipe to a 1.5-inch pipe using female NPT (FNPT) connections on both ends. Constructed from 304 stainless steel, this Schedule 40 fitting delivers corrosion resistance suitable for a wide range of fluid handling, plumbing, and light industrial piping systems. Rated at 150 psi, it handles typical service pressures found in commercial and residential installations. Licensed plumbers and pipefitters install this type of reducer when a line size reduction is required within a threaded piping system.
This reducer fits into threaded piping systems where a transition from 2-inch to 1.5-inch line size is needed. Typical applications include water supply lines, process piping, HVAC hydronic systems, and general-purpose plumbing assemblies. The FNPT x FNPT configuration is compatible with standard male NPT threaded pipe ends and fittings. Its 304 stainless steel construction makes it appropriate for environments where mild corrosion resistance is a requirement, including food-adjacent, marine-adjacent, and wet mechanical spaces.
Designed as an OEM-style replacement or new-installation fitting for Schedule 40 threaded piping systems using standard NPT connections in 2-inch to 1.5-inch reducer applications.
Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and local plumbing code requirements. Shut off and depressurize the affected piping system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to all male NPT threads before assembly. Do not overtighten threaded stainless steel fittings, as galling can occur and damage the threads permanently.
