Value Collection 6SPU1/4 Pipe Coupling 1/4 in 316 Ss

Product Description

The VALUE COLLECTION 6SPU1/4 is a 1/4-inch threaded pipe coupling machined from 316 stainless steel. It connects two sections of pipe using female NPT threads on both ends, making it a standard FNPT x FNPT inline connector. Rated to 150 psi at Schedule 40 wall thickness, it is suited for moderate-pressure piping systems carrying water, chemicals, or other compatible media. Plumbers, pipefitters, and maintenance technicians install this fitting in commercial and industrial piping runs where corrosion resistance is a priority.

This coupling is used in residential and light commercial plumbing, HVAC condensate and chilled-water piping, and industrial process lines where 316 stainless steel is specified for its improved chloride and corrosion resistance over 304-grade material. The small 1/4-inch size makes it common in instrument lines, chemical feed systems, and tight-space piping assemblies. Both connection ends accept standard NPT pipe threads, so it integrates directly into existing threaded piping infrastructure without adapters.

Key Features

• 316 stainless steel construction for superior corrosion and chloride resistance
• FNPT x FNPT threaded ends accept standard NPT pipe on both sides
• 150 psi pressure rating at Schedule 40
• 1/4-inch fitting size for small-diameter piping and instrument lines
• Inline coupling design for straight pipe-to-pipe connections

Compatibility

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

Installation Notes

A licensed plumber or pipefitter should isolate and depressurize the line before installation. Apply a thread sealant or PTFE tape rated for the fluid service to the male NPT threads before make-up. Tighten using pipe wrenches to a snug fit without over-torquing stainless threads, which are susceptible to galling. Follow applicable IPC or local plumbing code requirements for the specific fluid service and pressure rating.
