Value Collection 4SPU3/8 Pipe Coupling 3/8 in SS304

Product Description

The VALUE COLLECTION 4SPU3/8 is a 3/8 inch threaded pipe coupling constructed from 304 stainless steel. It connects two sections of pipe using female NPT threads on both ends, making it a straightforward inline joining fitting for a wide range of fluid and gas piping systems. Rated to 150 psi at Schedule 40, this coupling is built for reliability in demanding service environments. Licensed plumbers and pipefitters install this type of fitting in both new construction and repair work where a durable, corrosion-resistant threaded connection is required.

This coupling is suited for residential and light commercial plumbing, process piping, and mechanical systems where 3/8 inch threaded connections are specified. Its 304 stainless steel construction makes it appropriate for applications involving water, mild chemicals, or environments prone to corrosion. The FNPT x FNPT configuration allows direct thread engagement on both ends without adapters, streamlining installation on standard NPT-threaded pipe runs.

Key Features

• 304 stainless steel construction for corrosion resistance in wet and chemical-exposure environments
• FNPT x FNPT end connections for standard NPT thread engagement on both ends
• 150 psi pressure rating suitable for Schedule 40 piping systems
• 3/8 inch fitting size covers common small-diameter residential and commercial pipe runs
• Threaded connection type requires no welding or press tooling for installation

Compatibility

Designed as an OEM-style replacement or new-install fitting for Schedule 40 piping systems using standard 3/8 inch NPT threaded connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter using a pipe wrench and appropriate thread sealant or PTFE tape applied to the male NPT threads engaging this fitting. Shut off and depressurize the supply line and verify zero pressure before disassembling any existing fitting. Follow applicable plumbing codes, including IPC requirements, for thread engagement depth and sealant type based on the conveyed media. Do not overtighten, as stainless steel threads can gall if excessive torque is applied without proper lubrication.
