Midland Industries 62420MS 3 in Female Npt Coupling 304 Ss

Product Description

The MIDLAND INDUSTRIES 62420MS is a full-port threaded coupling designed to join two female NPT pipe ends in a straight-run configuration. Built from 304 stainless steel, this fitting delivers corrosion resistance suitable for water, mild chemical, and general industrial service lines. Both connection ports accept 3-inch female NPT threads at a 150 lb pressure class rating. The 3/8 thread pitch conforms to standard NPT taper specifications. This fitting is typically installed by licensed plumbers and pipefitters working on commercial or industrial piping systems where stainless steel material is specified for corrosion resistance or sanitary requirements.

The 62420MS is suited for use in commercial plumbing, industrial process piping, and mechanical systems requiring a 3-inch NPT threaded union point. Its 150 lb pressure class makes it appropriate for low-to-medium pressure service lines. The fitting is part of the SP-114 series of 304 stainless steel fittings, which covers a range of NPT threaded configurations for professional piping assemblies. This coupling is applicable in both new construction and retrofit applications where a threaded stainless steel connection is required.

Key Features

• 304 stainless steel construction for corrosion resistance in demanding service environments
• 3-inch female NPT on both ends for straight inline pipe joining
• 150 lb pressure class rating for low-to-medium pressure piping systems
• 3/8 NPT thread pitch conforming to standard taper thread specifications
• Part of the SP-114 series for consistent fitment across stainless steel NPT fitting configurations

Compatibility

Designed as an OEM-style threaded fitting for use with 3-inch NPT-threaded pipe in 150 lb class stainless steel piping assemblies. Compatible with standard NPT-threaded pipe and fittings meeting ASME B1.20.1 thread specifications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or applicable local standards. Shut down system pressure and drain the line before threading or unthreading any fitting. Apply appropriate thread sealant or PTFE tape to the male NPT threads being joined into this coupling. Do not over-tighten threaded connections, as stainless steel threads are susceptible to galling.
