Legend Valve 404-470 Hex Bushing 1/4x1/8 304 Ss

Product Description

The Legend Valve Fitting 404-470 is a hex bushing machined from 304 stainless steel, sized at 1/4 inch by 1/8 inch. A hex bushing is a threaded pipe fitting used to reduce from a larger pipe thread to a smaller one within the same connection point. The external hex profile allows a wrench to seat and torque the fitting securely without slippage. 304 stainless steel construction provides strong resistance to corrosion and oxidation, making it a reliable choice in wet, chemical-exposed, or outdoor service environments. This fitting is sold as a single unit and is the correct replacement or repair fitting when identified by part number 404-470.

Hex bushings in this size range are commonly used in plumbing, instrumentation, and light industrial piping systems where a 1/4 inch male NPT thread must connect to a 1/8 inch female NPT port. Typical applications include gauge ports, sensor taps, pressure test points, and branch connections on small-diameter pipe runs. The 304 stainless steel grade makes this fitting suitable for water service, compressed air lines, and many chemical systems where carbon steel fittings would corrode prematurely. Licensed plumbers and pipefitters are the primary installers in commercial and industrial settings, though this fitting also sees use in residential plumbing repairs and HVAC instrumentation work.

Key Features

• 304 stainless steel construction resists corrosion in wet and chemical-exposed environments
• Hex bushing design allows full wrench engagement for controlled installation torque
• 1/4 inch by 1/8 inch size reduces a larger threaded port to a smaller pipe connection
• Sold as a single unit for targeted repair or replacement work

Compatibility

Designed as an OEM-style replacement hex bushing for threaded pipe systems using 1/4 inch by 1/8 inch NPT connections in plumbing, instrumentation, and light industrial applications.

Installation Notes

This fitting is installed by a licensed plumber or pipefitter using a pipe wrench or adjustable wrench on the external hex. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly and follow IPC or applicable local plumbing code requirements for the specific system type. Do not overtighten stainless steel fittings against dissimilar metals, as galling can occur.
