Midland Industries 540684 Hex Pipe Reducer Bushing Steel

Product Description

The MIDLAND INDUSTRIES 540684 is a hex pipe reducer bushing designed to transition between a 1/2-inch male NPTF connection and a 1/4-inch female NPTF connection in steel pipe systems. Built from steel, this bushing delivers reliable sealing performance in hydraulic and fluid-transfer applications where a secure, leak-resistant threaded joint is required. The NPTF thread form creates a pressure-tight seal through thread interference, reducing reliance on additional sealants. The hex body allows for standard wrench installation and removal. At 0.095 pounds and compact dimensions, it fits easily into tight plumbing configurations without adding significant bulk or weight to an assembly.

This bushing is suited for residential and commercial hydraulic systems, steel pipe assemblies, and fluid-handling installations where a 1/2-inch line must be reduced to a 1/4-inch port or fitting. Typical applications include hydraulic circuits, compressed air lines, and general-purpose pipe systems that require a step-down in thread size. It is installed by licensed plumbers, hydraulic technicians, and pipefitters working with steel pipe adapter configurations.

Key Features

• 1/2-inch male NPTF x 1/4-inch female NPTF thread configuration for reliable pipe size reduction
• NPTF thread form provides pressure-tight interference seal
• Steel construction for durability in hydraulic and fluid-transfer service
• Hex body design enables installation and removal with standard wrenches
• Compact profile at 1.05 inches height and 0.75 inches length
• Rated to 375 degrees F operating temperature

Compatibility

Designed as an OEM-style replacement or direct-fit component for steel pipe systems using 1/2-14 male NPTF and 1/4-18 female NPTF threaded connections in hydraulic and general fluid-handling assemblies.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or hydraulic technician. Depressurize and isolate the system completely before removing or installing any threaded pipe fittings. Use a properly sized open-end or adjustable wrench on the hex body to achieve a secure fit without over-tightening, which can damage threads or crack fittings. Consult applicable codes such as the International Plumbing Code (IPC) for thread sealant requirements on NPTF joints in your jurisdiction.
