Value Collection 4SPU4 Stainless Steel Npt Coupling

Product Description

The VALUE COLLECTION 4SPU4 is a stainless steel pipe coupling with NPT (National Pipe Taper) threaded end connections. A coupling joins two sections of pipe in a straight run, maintaining a pressure-rated, leak-resistant seal in plumbing and piping systems. The stainless steel construction resists corrosion, making this fitting suitable for demanding environments where carbon steel or brass fittings may degrade. Licensed plumbers and pipefitters typically install this fitting in commercial and industrial piping systems. At 3.19 pounds, the 4SPU4 is a solid, full-weight fitting intended for durable, long-service applications.

This NPT coupling is used in residential and commercial plumbing, HVAC hydronic piping, process piping, and general-purpose fluid transfer systems. NPT threading is the standard tapered pipe thread in North American plumbing and mechanical systems, making this fitting broadly compatible with NPT-threaded pipe ends across a wide range of system types and pipe schedules. It ships as a single unit per package.

Key Features

• Stainless steel body provides corrosion resistance in wet, chemical, or outdoor environments
• NPT threaded end connections for standard North American tapered pipe thread fitment
• Coupling configuration joins two pipe sections in a straight run
• Single-piece package quantity for individual replacement or low-volume installations
• 5.06 inches height and 3.68 inches width allow for fit verification in tight spaces

Compatibility

Designed as a direct-fit replacement coupling for NPT-threaded pipe systems. Verify pipe thread size and schedule before installation, as no specific compatible model numbers or pipe sizes were provided with this product listing.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Depressurize and isolate the pipe section before removing any existing fitting. Apply thread sealant tape or pipe dope to NPT threads before assembly and tighten to hand-tight plus the appropriate number of turns for the pipe size per fitting manufacturer and code guidelines. Do not overtighten, as NPT fittings are tapered and can crack under excessive torque.
