Midland Industries 440488 Beaded Insert Adapter 1/2 in Steel

Product Description

The MIDLAND INDUSTRIES 440488 is a beaded insert adapter designed to connect a 1/2-inch beaded stem hose end to a 1/2-inch male NPTF threaded port. Constructed from steel, this fitting is built for hydraulic line assemblies where a secure, leak-resistant connection between a flexible hose and a threaded component is required. The beaded stem design mechanically retains the hose end, reducing the risk of blowoff under pressure. This fitting is part of the 4404 Series of steel beaded hose fittings and is a standard component in hydraulic fluid conveyance systems. Installation is typically performed by hydraulic technicians and fluid power specialists.

The 440488 is used in hydraulic system plumbing where a flexible hose must terminate at a male NPTF threaded port on a valve, manifold, cylinder, or pump. The NPTF thread form creates a pressure-tight seal through thread interference without requiring a separate sealant, though thread sealant is commonly applied in field installations. This fitting suits industrial, mobile, and off-highway hydraulic applications where steel construction and reliable mechanical hose retention are required.

Key Features

• 1/2-inch beaded stem end retains hose mechanically for blowoff resistance
• 1/2-inch male NPTF thread provides a pressure-tight connection at the port end
• Steel construction for durability in hydraulic service environments
• Part of the 4404 Series steel beaded hose fittings line
• Minimum order quantity of 1 unit

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic hose assemblies requiring a 1/2-inch beaded stem to 1/2-inch male NPTF connection in steel.

Installation Notes

Installation is typically performed by a licensed hydraulic technician or fluid power specialist. Depressurize and bleed the hydraulic system fully before removing or installing any fittings. Apply an appropriate thread sealant to the male NPTF threads per the system manufacturer and applicable fluid power standards. Do not overtighten; use a backup wrench on adjacent fittings to avoid twisting hose assemblies.
