Parker BD11543-20-16-1 Code 61 Straight Hose Fitting

Product Description

The PARKER BD11543-20-16-1 is a Code 61 straight hydraulic hose fitting designed for high-pressure fluid power systems. Machined from steel with SAE-standard threaded connections, this fitting attaches directly to compatible hydraulic hoses at a 1-inch inside diameter (hose size 16) and accepts a 1-1/4-inch thread. The straight configuration simplifies inline routing without angular offset. At 3.19 inches overall length, it is a compact, purpose-built end fitting suited for industrial and mobile hydraulic circuits. Hydraulic technicians and fluid power mechanics install this component to terminate hose assemblies where a leak-free, high-integrity Code 61 flange or threaded interface is required.

This fitting is intended for use in hydraulic hose assemblies operating in industrial equipment, mobile machinery, and fluid power systems requiring Code 61 straight terminations. It conforms to ISO 12151-3-S-L, which governs dimensions and performance for hose fittings used in high-pressure hydraulic applications. The 1-inch ID bore accommodates hose size 16, a common sizing used in mid- to high-flow hydraulic circuits. The steel construction provides durability under sustained pressure cycling.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power assembly practices. Depressurize and fully isolate the hydraulic circuit before disassembling any hose or fitting. Follow the hose manufacturer's assembly instructions for proper insertion depth and swaging or crimping procedures, as applicable. Verify thread engagement and fitting seating before returning the system to pressure.
