Value Collection 4RSB11/4*1 Pipe Reducer 1-1/4 X 1 in 304 Ss

Product Description

The VALUE COLLECTION 4RSB11/4*1 is a threaded pipe reducer fitting designed to connect a 1-1/4 inch female NPT line to a 1 inch female NPT line in piping systems. Constructed from 304 stainless steel and rated for Schedule 40 service, this fitting handles up to 150 psi of working pressure. The all-threaded FNPT x FNPT connection makes it compatible with standard NPT pipe assemblies without the need for special tools or flanged joints. Plumbers and pipefitters install this type of reducer when transitioning between pipe sizes in water supply, process piping, and fluid handling systems.

This reducer is suited for residential and light commercial plumbing, industrial fluid distribution, and process piping installations where a step-down from 1-1/4 inch to 1 inch pipe is required. The 304 stainless steel construction provides corrosion resistance in wet, humid, or mildly corrosive environments. It is commonly used in water supply lines, HVAC condensate systems, and general-purpose pipe runs where NPT threaded fittings are specified.

Key Features

• Reduces from 1-1/4 inch FNPT to 1 inch FNPT in a single fitting
• 304 stainless steel construction for corrosion resistance in wet and mildly corrosive service
• Threaded FNPT x FNPT connection — no welding or flanging required
• 150 psi pressure rating suitable for Schedule 40 piping systems
• Compact form factor fits standard NPT threaded pipe assemblies

Compatibility

Designed as an OEM-style threaded reducer for use in standard NPT Schedule 40 piping systems requiring a 1-1/4 inch to 1 inch female-to-female reduction.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and local plumbing code requirements. Shut off and depressurize the system fully before removing existing fittings or installing this reducer. Apply thread sealant tape or compound to the male NPT threads before assembly, and tighten to hand-tight plus the appropriate number of turns per standard practice — do not overtighten stainless threaded fittings, as galling can occur. Pressure-test the assembled joint before returning the system to service.
