Value Collection 4RSB1/4*1/8 Pipe Reducer 1/4 X 1/8 in 304 Ss

Product Description

The VALUE COLLECTION 4RSB1/4*1/8 is a threaded pipe reducer fitting designed to transition from a 1/4-inch to a 1/8-inch female NPT connection in pressurized piping systems. Constructed from 304 stainless steel and rated to 150 psi, this Schedule 40 fitting delivers reliable corrosion resistance in both wet and dry service environments. The FNPT x FNPT end connections accept standard tapered pipe threads on both ends, making it a direct-fit solution for reducing line size within plumbing, compressed air, instrumentation, or light industrial piping assemblies. Licensed plumbers, pipefitters, and HVAC mechanics routinely use fittings of this type when adapting supply lines or instrument ports.

This reducer is suited for residential and light commercial applications where a 1/4-inch pipe line must step down to a 1/8-inch port or branch. Typical installations include gauge ports, instrument tap connections, compressed air distribution headers, and small-bore plumbing manifolds. The 304 stainless steel construction makes it a practical choice in environments subject to moisture, mild chemical exposure, or sanitary requirements where carbon steel or brass may be less appropriate.

Key Features

• 304 stainless steel construction resists corrosion in wet and mildly corrosive service environments
• 150 psi pressure rating suitable for Schedule 40 piping systems
• FNPT x FNPT threaded connections on both ends for tool-free dry-fit alignment before final makeup
• 1/4 inch to 1/8 inch reducing configuration for instrument ports and small-bore branch connections
• Compact form factor fits in tight inline or manifold installations

Compatibility

Designed as a standard threaded pipe reducer for use in Schedule 40 piping systems with 1/4-inch and 1/8-inch NPT-threaded components.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC or local mechanical code requirements. De-pressurize and drain the affected piping section completely before removing any existing fittings or making new connections. Apply an appropriate thread sealant or PTFE tape to the male NPT threads mating into this fitting to ensure a leak-free joint. Do not over-torque threaded stainless fittings, as galling can occur and damage the threads.
