Midland Industries 56052 Welded Pipe Nipple 3/8 in Sch 40

Product Description

The MIDLAND INDUSTRIES 56052 is a welded steel pipe nipple designed for threaded piping systems in plumbing, mechanical, and industrial applications. This nipple measures 8 inches in length with 3/8 inch male pipe thread (MPT) on both ends, a 0.091 inch wall thickness, and a Schedule 40 pressure rating. The galvanized steel construction provides corrosion resistance suited to wet and exposed environments. At a rated working pressure of 700 psi and a temperature range of -150 to 200 degrees F, it handles the demands of general-purpose pipe assembly. Licensed plumbers and pipefitters are the typical installers.

This nipple is used in residential and light commercial piping systems where a short, fixed-length threaded connection is required. Common applications include water supply lines, gas distribution risers, and compressed air systems. The 3/8 inch diameter and SCH 40 wall rating make it a standard choice for branch connections and close-coupled fittings in both new construction and retrofit work. Thread dimensions conform to ANSI B1.20.1, ensuring compatibility with standard NPT fittings throughout the system.

Key Features

• Galvanized steel construction resists corrosion in wet and exposed piping environments
• Schedule 40 wall thickness rated to 700 psi working pressure
• 3/8 inch MPT on both ends with 0.6 inch thread engagement length
• ANSI B1.20.1 thread dimensional standard for consistent fit with NPT fittings
• Temperature range of -150 to 200 degrees F suits a broad range of fluid and gas service conditions
• 0.091 inch wall thickness provides structural integrity for high-pressure branch connections

Compatibility

Designed as a standard SCH 40 galvanized steel threaded nipple compatible with 3/8 inch NPT fittings, valves, and pipe connections conforming to ANSI B1.20.1 thread standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off the supply line and depressurize the system fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten to a snug fit using pipe wrenches without over-torquing the fitting. Verify system pressure rating is not exceeded after returning the line to service.
