Midland Industries 62481MS 4 in Female Npt Pipe Cap 304 Ss

Product Description

The MIDLAND INDUSTRIES 62481MS is a 4-inch female NPT pipe cap manufactured from 304 stainless steel, rated for 150 lb pressure service. This fitting is designed to terminate open pipe ends in piping systems where corrosion resistance and mechanical durability are required. The female NPT thread with a 4-8 thread specification allows direct connection to standard male-threaded pipe ends. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting during system shutdowns, pressure testing, or to permanently or temporarily close off unused pipe runs.

This pipe cap is suited for use in plumbing, process piping, and fluid handling systems where 304 stainless steel is specified for corrosion resistance. Typical applications include water lines, chemical-compatible fluid systems, and commercial or industrial installations requiring 150 lb class fittings. Its 4-inch connection size makes it appropriate for larger-diameter piping runs found in commercial mechanical and process environments.

Key Features

• 4-inch female NPT connection for direct installation onto male-threaded pipe ends
• 304 stainless steel construction provides corrosion resistance in wet and chemically active environments
• 150 lb pressure class rating suitable for standard commercial and industrial service
• 4-8 thread specification ensures compatibility with standard NPT pipe threading
• SP-114 series fitting conforming to recognized stainless steel fitting standards

Compatibility

Designed as an OEM-style replacement or direct-install fitting for 4-inch male NPT threaded pipe ends in 150 lb class piping systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing and mechanical codes such as the IPC. Depressurize and drain the piping system completely before removing any existing fittings or installing this cap. Apply appropriate thread sealant or PTFE tape to male threads before engagement. Do not over-torque stainless steel fittings, as galling on threaded connections can occur without proper lubrication.
