The VALUE COLLECTION 4HB2*1 is a threaded pipe bushing designed to reduce a 2-inch pipe connection down to a 1-inch pipe connection within a piping system. Constructed from 304 stainless steel, it delivers solid corrosion resistance in demanding wet, chemical, or outdoor environments. The bushing features a male NPT (MNPT) inlet and a female NPT (FNPT) outlet, both threaded per Schedule 40 standards, with a pressure rating of 150 psi. At 1-7/16 inches in length, it is a compact inline reducer suited for process piping, plumbing, and mechanical systems where stainless steel fittings are specified.
This bushing is used in residential and commercial piping installations where a reduction from 2-inch to 1-inch pipe diameter is required. Common applications include water supply lines, compressed air systems, fluid transfer systems, and process piping that requires corrosion-resistant stainless steel fittings. It is typically installed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for threaded pipe connections.
Designed as an OEM-style replacement or direct-fit addition for standard Schedule 40 threaded piping systems requiring a 2-inch to 1-inch MNPT x FNPT reducing bushing in stainless steel.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes. Depressurize and drain the piping system fully before removing or installing any fitting. Apply thread sealant or PTFE tape to male threads before assembly to ensure a leak-free joint. Do not overtighten threaded stainless steel fittings, as galling of the threads can occur.
