Parker BD-115771212-1 Code 61 Straight Hose Fitting

Product Description

The PARKER BD-115771212-1 is a Code 61 straight hydraulic hose fitting designed for high-pressure fluid conveyance in hydraulic systems. Constructed from steel with a flanged connection type, this SAE-series fitting attaches directly to compatible hydraulic hose ends and mating flanged ports. It features a 0.75-inch hose inside diameter and a 3/4-inch thread size, with an overall length of 4.23 inches. The straight geometry simplifies routing in applications where inline connections are required. Installation is typically performed by hydraulic technicians and fluid power mechanics working on mobile equipment or industrial hydraulic circuits.

This fitting is specified for use with Parker 787TC and 797TC hydraulic hose. It is suited to high-pressure hydraulic lines in mobile and industrial equipment where Code 61 four-bolt flange connections are the required standard. The flanged interface provides a reliable seal under cyclic pressure loads common in heavy-equipment hydraulic circuits. The steel construction supports demanding service environments where corrosion resistance is secondary to mechanical strength and pressure integrity.
