Value Collection 4SPU3/4 Pipe Coupling 3/4 in 304 Ss

Product Description

The VALUE COLLECTION 4SPU3/4 is a 3/4-inch threaded pipe coupling machined from 304 stainless steel. It connects two sections of pipe using female NPT threads on both ends, making it a standard FNPT x FNPT inline joining fitting. Rated to 150 psi, it is compatible with Schedule 40 piping systems. Plumbers and pipefitters install this coupling in fluid and gas distribution lines where corrosion resistance and reliable thread engagement are required. The 304 stainless steel construction resists rust and chemical attack in a wide range of service environments.

This coupling is suited for residential and light commercial plumbing, HVAC condensate and hydronic piping, and industrial fluid transfer applications. The threaded FNPT x FNPT configuration allows installation without welding or special tooling, making it practical for repair work and new construction alike. Schedule 40 system compatibility ensures broad use across standard piping assemblies found in mechanical rooms, utility lines, and process piping.

Key Features

• 3/4-inch fitting size for standard pipe connections
• 304 stainless steel construction for corrosion resistance
• FNPT x FNPT end connections for all-female threaded assembly
• 150 psi pressure rating suitable for typical plumbing and hydronic service
• Schedule 40 compatible for use in common pipe system configurations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 threaded pipe systems using 3/4-inch NPT connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC and IFGC guidelines. Shut off and depressurize the line before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male NPT threads before making up the connection. Do not overtighten; use a pipe wrench with a backup wrench on adjacent fittings to avoid stressing the pipe.
