Value Collection 4SPU1/4 Pipe Coupling 1/4 in 304 Ss

Product Description

The VALUE COLLECTION 4SPU1/4 is a 1/4 inch threaded pipe coupling manufactured from 304 stainless steel. It connects two sections of pipe using female NPT (FNPT) threads on both ends, making it a standard union fitting for straight-run piping assemblies. Rated at 150 psi and conforming to Schedule 40 dimensions, this coupling suits low-to-moderate pressure service lines in plumbing, HVAC piping, and light industrial applications. The 304 stainless steel construction provides corrosion resistance in wet or chemically active environments. Licensed plumbers and pipefitters are the typical installers for this type of fitting in commercial and residential settings.

This coupling is suited for use in residential and light commercial piping systems where a compact, corrosion-resistant threaded union is required. Common applications include water supply lines, condensate drain assemblies, compressed air distribution, and process piping where 304 stainless steel is specified for its resistance to oxidation and general corrosion. The FNPT x FNPT configuration accepts standard NPT-threaded pipe or nipples on both sides for quick, tool-assisted assembly.

Key Features

• 304 stainless steel construction resists corrosion in wet and mildly corrosive service environments
• FNPT x FNPT end connections accept standard NPT-threaded pipe and nipples on both sides
• 150 psi pressure rating suitable for low-to-moderate pressure piping systems
• Schedule 40 dimensions for compatibility with standard pipe sizing
• Compact 1/4 inch fitting size for tight-clearance or small-bore piping runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40, 1/4 inch NPT-threaded piping systems using standard pipe and nipple components.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC or local plumbing code requirements. Shut off the water or fluid supply and relieve system pressure before threading or unthreading any fitting. Apply PTFE tape or pipe thread sealant compound to the male NPT threads before making up the joint. Use a proper pipe wrench or strap wrench to tighten; do not over-tighten, as this can crack or distort stainless steel fittings.
