Midland Industries 57307TV Pipe Nipple 6 in Sch 40 Steel

Product Description

The MIDLAND INDUSTRIES 57307TV is a seamless black steel pipe nipple designed for use in industrial and commercial piping systems. It features a 6-inch threaded connection on one end and a 6-inch grooved connection on the other, allowing it to bridge threaded and grooved piping configurations in a single fitting. Built to Schedule 40 wall thickness and conforming to ANSI B1.20.1 thread dimensional standards, this nipple delivers consistent fitment and reliable pressure-rated performance. Weighing 6.55 pounds, it is suited for permanent piping installations where a robust steel fitting is required. Licensed plumbers and pipefitters handle installation in both new construction and retrofit applications.

This fitting is used in residential and commercial black steel piping systems, most commonly in fire suppression, gas distribution, and mechanical piping layouts where threaded-to-grooved transitions are required. Its 6-inch diameter and 6-inch body length make it appropriate for main line transitions or header connections. The Schedule 40 wall rating supports a wide range of working pressures typical of these applications. It carries a temperature rating of -200 to 150 degrees F, covering the operating range of most mechanical system environments where black steel pipe is specified.

Key Features

• Seamless black steel construction for consistent wall integrity throughout the fitting body
• Threaded x grooved end connections allow direct transition between threaded and grooved piping systems
• Schedule 40 wall thickness meets standard pressure ratings for commercial and industrial piping
• ANSI B1.20.1 compliant threading ensures dimensional compatibility with standard NPT fittings
• Temperature range of -200 to 150 degrees F supports a broad range of mechanical applications
• 6-inch diameter and 6-inch body length suit main line and header transition installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 black steel piping systems using standard NPT threaded and grooved pipe connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and IFGC codes for the intended service. Shut off and depressurize the system completely before removing any existing fittings or making new connections. Use appropriate pipe thread sealant rated for the service medium on the threaded end, and follow the grooved coupling manufacturer's specifications when engaging the grooved end. Do not over-tighten the threaded connection, as this can damage threads and compromise the seal.
