Merit Brass 4548-400 Pipe Nipple 3 Inch Sch 80 Ss 304

Product Description

The MERIT BRASS 4548-400 is a seamless stainless steel pipe nipple designed for demanding piping applications where corrosion resistance and pressure integrity are required. Constructed from Grade 304/304L stainless steel and manufactured to Schedule 80 wall thickness, this nipple delivers the dimensional consistency and strength that licensed plumbers and pipefitters expect in both industrial and commercial installations. At 2.668 pounds, it is a solid, full-weight fitting appropriate for high-pressure or high-purity fluid systems. It suits systems where standard carbon steel fittings would be vulnerable to chemical attack or rust.

This nipple is suited for use in commercial and industrial plumbing, process piping, HVAC hydronic systems, and steam applications where stainless steel is specified by code or engineering requirement. The 3-inch pipe size and Schedule 80 wall thickness make it appropriate for high-pressure fluid conveyance lines. It is commonly installed by licensed plumbers, pipefitters, and mechanical contractors working to ASME or ASTM piping specifications.

Key Features

• Grade 304/304L dual-certified stainless steel for corrosion resistance in wet and chemical environments
• Schedule 80 wall thickness for elevated pressure ratings compared to standard Schedule 40
• Seamless construction eliminates weld seams that can be points of failure under pressure cycling
• 3-inch pipe size with matching 3-inch thread size for direct threaded installation
• Single-piece unit packaging with no minimum order quantity beyond one piece

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch Schedule 80 stainless steel threaded piping systems conforming to standard NPT thread specifications.

Installation Notes

Installation of threaded stainless steel pipe nipples should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Isolate and depressurize the piping system completely before removing or installing any threaded fitting. Use thread sealant or PTFE tape rated for the service fluid and pressure range. Avoid over-torquing stainless steel threads, as galling is a known risk with austenitic stainless fittings.
