The ASC Engineered Solutions 36HB1020012L is a brass hex bushing designed to reduce a larger female pipe thread to a smaller male pipe thread within a piping system. This fitting accepts a 2-inch female connection and steps down to a 1-1/4-inch male connection, making it a practical solution for transitioning between pipe sizes without additional couplings or adapters. Built from brass, it offers reliable corrosion resistance and durability in a range of plumbing and fluid-handling applications. Licensed plumbers and pipefitters are the typical installers for this type of threaded fitting.
This hex bushing is suited for residential and light commercial plumbing systems where a threaded pipe size reduction is needed in-line. The external hex profile allows for easy installation and removal using standard pipe wrenches or open-end wrenches. Its catalog designation 125 indicates the pressure class rating applicable to this fitting, making it appropriate for low- to moderate-pressure water and compatible fluid service lines.
Designed as an OEM-style threaded replacement fitting for residential and commercial plumbing systems requiring a 2-inch to 1-1/4-inch pipe thread reduction in brass.
Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the system before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as brass threads can be damaged by excessive torque.
