Parker 11L43-4-4 Nptf Swivel Elbow 90 Deg 0.25 in Id

Product Description

The PARKER 11L43-4-4 is a male NPTF pipe swivel elbow fitting designed for hydraulic hose assemblies. Built from steel with a 90-degree elbow shape, it connects hydraulic hose to threaded port locations where a right-angle transition is required. The fitting features a 0.25 inch (1/4 inch) hose inside diameter and a 1/4 inch NPTF threaded shaft, making it a standard size-4 hose fitting in the Parker Series 43 lineup. Hydraulic technicians and fluid power mechanics install this type of swivel elbow when routing hose around obstructions or reducing stress on the hose end at the port connection.

This fitting is suited for mobile hydraulic systems, industrial machinery, and fluid power circuits where a 90-degree hose-to-port connection is needed. It is rated for use in assemblies requiring a leak-free NPTF thread engagement. The swivel design allows the hose to be positioned after assembly without twisting the hose body, which is particularly useful in tight routing situations common in agricultural equipment, construction machinery, and plant hydraulics.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Relieve all hydraulic system pressure and depressurize the reservoir before disconnecting or installing any fitting. NPTF dry-seal threads require proper thread engagement to achieve a leak-free seal without additional sealant, though thread sealant compatible with the hydraulic fluid may be used per system requirements. Inspect threads for damage before assembly and avoid cross-threading.
