Parker BD10543-16-12 Hydraulic Hose Fitting 0.75 in

Product Description

The PARKER BD10543-16-12 is a male rigid straight fitting designed for hydraulic hose assemblies. It features a 0.75 inch (3/4 inch) hose inside diameter, a 1-5/16-12 thread size, and a Male O-Ring Boss (ORB) shaft type. Constructed from steel, this fitting provides a threaded, leak-resistant connection point in high-pressure hydraulic circuits. With an overall length of 2.81 inches, it is a compact, direct-replacement component used in industrial, mobile, and fluid-power applications. Hydraulic technicians and fluid-power mechanics install this fitting when assembling or repairing hose runs that require a rigid, straight male ORB termination.

This fitting is suited for hydraulic systems requiring a reliable straight male rigid end connection in size 12 hose configurations. It is compatible with a broad range of Parker hose series and is commonly found in mobile equipment, industrial machinery, and fluid-power installations where steel construction and ORB threading are specified. The 1-5/16-12 thread engages standard ORB port bosses, making it a routine component in hose-assembly fabrication shops and field repair work.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power mechanic. Depressurize and bleed the hydraulic system completely before disconnecting or installing any fittings. Inspect the ORB port boss and fitting threads for damage or contamination before assembly, and apply the appropriate thread lubricant or sealant per the equipment manufacturer's requirements. Torque to the equipment or system specification; do not use general values not verified for this application.
