Midland Industries 63610MS 3in Fnpt X Fnpt 316 Ss Union 150lb

Product Description

The MIDLAND INDUSTRIES 63610MS is a 3-inch female NPT x 3-inch female NPT union fitting machined from 316 stainless steel. It carries a 150 lb pressure class rating and is designed for inline pipe connections that require periodic disassembly without disturbing the surrounding piping. The three-piece union design allows technicians to break the line cleanly for maintenance, inspection, or component replacement. At 5.76 pounds, this is a substantial fitting suited to demanding industrial and commercial plumbing applications where corrosion resistance and mechanical strength are both required.

This union is appropriate for use in chemical processing lines, marine piping systems, food and beverage facilities, and commercial plumbing installations where 316 stainless steel is specified for its elevated chloride and corrosion resistance compared to 304 SS. It is sized for 3-inch nominal pipe and connects two female NPT threaded ends, making it a direct in-line union for threaded pipe systems. Licensed plumbers and pipefitters working on industrial or high-corrosion-environment projects are the primary installers of this fitting.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh or chloride-rich environments

• 150 lb pressure class rating suitable for commercial and light industrial service
• Three-piece union design allows line separation without cutting or unthreading adjacent pipe
• SP-114 series fitting with consistent dimensional standards across the product family

Compatibility

Designed for use with 3-inch nominal threaded pipe systems requiring 150 lb class 316 stainless steel union fittings. Part of the SP-114 316 SS fittings series.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes such as the IPC. Depressurize and drain the line completely before disassembling or installing this union. Apply an appropriate thread sealant rated for stainless steel and the service media before making up the NPT connections. Do not overtighten NPT threads; follow standard tapered thread engagement practices to avoid galling the stainless steel threads.
