Midland Industries 57307V Seamless Pipe Nipple Sch 40

Product Description

The MIDLAND INDUSTRIES 57307V is a seamless black steel pipe nipple designed for grooved-end piping systems in commercial and industrial plumbing, fire protection, and mechanical applications. This nipple measures 6 inches in length with a 6-inch diameter and features grooved connections on both ends, making it compatible with standard grooved couplings and fittings. Built to Schedule 40 wall thickness and conforming to ANSI B1.20.1 dimensional standards, it delivers the structural integrity required for demanding fluid-handling systems. Licensed plumbers and pipefitters are the typical installers for this type of fitting.

This nipple is suited for use in black steel piping systems where grooved mechanical joining is specified. Common applications include commercial HVAC hydronic systems, wet-pipe and dry-pipe fire suppression headers, industrial process piping, and chilled or hot water distribution. The grooved-end configuration supports rapid assembly with grooved couplings without threading or welding. Its black steel finish and SCH 40 rating make it appropriate for above-ground and concealed-space installations within the rated temperature range of -200 to 150 degrees F.

Key Features

• Seamless steel construction provides consistent wall thickness and reliable pressure performance
• Grooved x grooved end connections for use with standard mechanical grooved couplings
• Schedule 40 wall thickness conforming to ANSI B1.20.1 dimensional standards
• Rated for service from -200 to 150 degrees F
• Black finish suitable for standard steel piping systems
• 6-inch length and 6-inch diameter for direct inline installation or extension spools

Compatibility

Designed as an OEM-style replacement or new-installation fitting for black Schedule 40 steel grooved piping systems using standard grooved couplings and fittings per the groove x groove configuration.

Installation Notes

Installation of grooved pipe nipples is typically performed by licensed plumbers or pipefitters in accordance with applicable IPC and NFPA standards. Depressurize and drain the piping system fully before removing or installing any fittings. Inspect groove dimensions for conformance to the coupling manufacturer's specifications before assembly. Follow the coupling manufacturer's torque and gasket seating procedures when securing grooved connections.
