Value Collection 4RSB1*3/8 Pipe Reducer 1x3/8 in Sch 40

Product Description

The VALUE COLLECTION 4RSB1*3/8 is a Schedule 40 pipe reducer fitting designed to transition between a 1-inch pipe and a 3/8-inch pipe in plumbing and piping systems. Reducers like this one allow technicians to step down pipe diameter within a run, connecting two sections of different sizes without additional adapters. The Schedule 40 rating indicates a standard wall thickness appropriate for general-purpose pressure applications. This fitting is sold individually and is suited for installation by licensed plumbers or experienced mechanical contractors.

This reducer is applicable in residential and light commercial plumbing systems where a diameter transition from 1 inch to 3/8 inch is required. Typical install scenarios include supply line transitions, branch takeoffs, and equipment connections where flow must be reduced to a smaller downstream pipe size. It is compatible with standard Schedule 40 pipe systems and meets conventional plumbing fitment requirements for that pipe schedule.

Key Features

• Reduces pipe diameter from 1 inch to 3/8 inch in a single fitting
• Schedule 40 wall thickness for standard-duty pressure applications
• Compact form factor suited for tight plumbing runs
• Single-unit packaging for individual replacement or repair jobs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard Schedule 40 pipe systems requiring a 1-inch to 3/8-inch diameter reduction.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off the water supply and depressurize the line before removing any existing fittings or cutting pipe. Ensure mating pipe ends are cut square, deburred, and clean before joining. Do not overtighten threaded connections, as this can crack fittings or strip threads.
