Midland Industries 4604O8 Beaded Insert 1/2 in Steel Fitting

Product Description

The MIDLAND INDUSTRIES 4604O8 is a steel beaded hose insert fitting from the 4604 Series, designed to connect a 1/2-inch beaded stem hose end to a 1/2-inch male O-ring boss (ORB) port. The beaded stem retains the hose securely when a clamp is applied, while the male ORB thread end seals against an O-ring seat on the receiving port, eliminating the need for thread sealants at that connection. At 0.12 pounds and measuring 2.35 inches in length, this compact fitting is suited for hydraulic fluid transfer lines in mobile and industrial equipment. Installation is typically performed by hydraulic technicians and fluid power specialists.

This fitting is used in hydraulic plumbing applications where a flexible hose must terminate at an O-ring boss port on a pump, valve, manifold, or cylinder. It is appropriate for residential and commercial-grade hydraulic systems in agricultural, construction, and industrial machinery. The 4604 Series designation indicates a beaded hose to male O-ring configuration, making this fitting a standard choice when routing push-on or clamp-style hose to ORB-ported components.

Key Features

• Beaded stem end retains hose firmly under clamp load, reducing blowoff risk

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic systems requiring a 1/2-inch beaded stem hose connection to a 1/2-inch male O-ring boss port.

Installation Notes

Depressurize and fully drain the hydraulic circuit before removing or installing any fitting. Inspect the O-ring on the boss end for damage before assembly and replace if worn. A hydraulic technician should verify the ORB port thread size and confirm hose clamp torque per system specifications. Follow applicable fluid power safety standards and equipment manufacturer guidelines during service.
