Midland Industries 5406206 Hex Pipe Reducer Bushing Steel

Product Description

The MIDLAND INDUSTRIES 5406206 is a hex pipe reducer bushing designed to reduce pipe thread size from a 1-1/4-inch male NPTF connection to a 3/8-inch female NPTF connection. Constructed from steel, it is suited for hydraulic and fluid system applications where a reliable, leak-resistant threaded reduction is required. The NPTF (National Pipe Taper Fuel) thread form creates a pressure-tight seal without requiring additional thread sealant, though sealant is commonly applied in practice. The hex body allows for standard wrench engagement during installation. With a maximum temperature rating of 375 degrees F, this bushing handles demanding service conditions in compressed air, hydraulic, and compatible fluid lines.

This bushing is used in hydraulic piping systems, compressed air assemblies, and general industrial plumbing where a 1-1/4-inch line must be reduced to a 3/8-inch port or fitting. It is part of the MIDLAND INDUSTRIES 5406 Series of hex pipe reducer bushings and falls within the steel pipe adapters product family. Typical install scenarios include manifold ports, pump inlets and outlets, valve bodies, and equipment headers where thread size transitions are needed without additional adapter fittings.

Key Features

• 1-1/4-inch male NPTF x 3/8-inch female NPTF thread configuration for in-line size reduction
• Steel construction for strength and durability in hydraulic and fluid service
• Hex body design allows secure wrench engagement for proper torque application
• Thread spec: 1-1/4-11-1/2 NPTF male x 3/8-18 NPTF female
• Rated for service up to 375 degrees F
• NPTF thread form provides a pressure-tight mechanical seal

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic and fluid piping systems requiring a 1-1/4-inch male NPTF to 3/8-inch female NPTF threaded reduction in steel pipe adapter applications.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or hydraulic system technicians. Shut down and depressurize the system fully before removing or installing any threaded fittings. Apply thread sealant or PTFE tape per the system manufacturer and applicable code requirements. Engage the hex body with an appropriately sized wrench and avoid over-tightening, which can crack or distort threaded ports.
