Midland Industries 62171MS 4-in Npt 90-deg Street Elbow 304 Ss

Product Description

The MIDLAND INDUSTRIES 62171MS is a 90-degree street elbow fitting designed for inline directional changes in threaded piping systems. Machined from 304 stainless steel, it offers solid corrosion resistance in wet, chemical-exposed, and outdoor environments. The fitting connects a 4-inch male NPT end directly to a 4-inch female NPT end, eliminating the need for a separate nipple between fittings. It is rated at a 150 lb pressure class with a 4-8 thread specification. Plumbers, pipefitters, and mechanical contractors install this fitting in industrial, commercial, and heavy-duty plumbing applications where stainless steel construction is required.

The 62171MS is suited for use in commercial and industrial piping systems that require a 90-degree direction change with NPT threaded connections. Its street configuration - male NPT on one end, female NPT on the other - allows it to thread directly into a valve, tee, or other female-threaded fitting without an intermediate coupling. Typical installations include process piping, water service lines, and mechanical systems where corrosion resistance and pressure integrity are priorities.

Key Features

• 90-degree street elbow configuration with 4-inch male NPT inlet and 4-inch female NPT outlet
• 304 stainless steel construction for corrosion resistance in wet and chemical environments
• 150 lb pressure class rating suitable for commercial and industrial service
• 4-8 thread specification for consistent, leak-resistant engagement
• Street design threads directly into female-threaded fittings without a separate nipple

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch NPT threaded piping systems requiring a 90-degree street elbow in the SP-114 304 stainless steel fitting series.

Installation Notes

This fitting is typically installed by licensed plumbers or pipefitters working under applicable IPC or mechanical code requirements. Shut off and depressurize the affected piping system before beginning work. Use appropriate thread sealant or PTFE tape on all NPT connections to ensure a leak-free joint. Do not over-torque stainless steel fittings, as galling of the threads can occur.
