Brennan 10551 Steel Flared Tube Connector 3/4 in Od

Product Description

The BRENNAN 10551 is a steel flared tube connector designed for hydraulic and fluid system plumbing applications. It features a 37-degree flare seat on one end and an O-ring boss (ORB) thread on the other, creating a reliable Flare x ORB end configuration. The thread size is 1-1/16-12 on the ORB end and 3/4-16 on the flare end, with a tube outside diameter of 3/4 inches. Constructed from steel, this connector provides the strength and durability needed for pressurized fluid lines in demanding service environments. Licensed tradespeople and fluid power technicians are the primary installers of this type of fitting.

This connector is used in hydraulic systems, fluid power circuits, and industrial plumbing applications where a transition between a 37-degree flared tube and an O-ring boss port is required. It is suited for both mobile and stationary hydraulic equipment. The 3/4-inch tube OD size is common in mid-range hydraulic line assemblies found in commercial and industrial settings. Package quantity is 2 units per package.

Compatibility

Designed as a standard 37-degree Flare x ORB connector for hydraulic and fluid power systems requiring a 3/4-inch OD tube connection with a 1-1/16-12 x 3/4-16 thread interface.

Installation Notes

Installation is typically performed by licensed hydraulic technicians or fluid power specialists. De-pressurize and fully isolate the hydraulic circuit before removing or installing any fittings. Inspect the flare seat and O-ring boss port for burrs or debris before assembly, and ensure the O-ring is properly seated and lubricated before torquing. Follow the equipment manufacturer and relevant industry standards for proper assembly procedures.
