Parker 11L43-12-12 Nptf Swivel Elbow Hose Fitting 3/4 in

Product Description

The PARKER 11L43-12-12 is a male NPTF pipe swivel elbow fitting designed for hydraulic hose assemblies. It features a 90-degree elbow configuration with a 0.75 inch (12 mm) hose inside diameter and a 3/4 inch NPTF threaded connection. Constructed from steel, this fitting provides the durability required in high-pressure hydraulic plumbing applications. The swivel design allows for rotational alignment during assembly, reducing hose twist and simplifying routing in tight or angled installations. It is part of Parker's Series 43 fitting line and is installed by hydraulic system technicians and industrial maintenance professionals.

This fitting is suited for use in industrial and mobile hydraulic systems where a 90-degree directional change is required at the hose-to-port connection. The threaded NPTF interface creates a dry-seal connection, minimizing the risk of leakage without the need for additional sealant in most applications. It is appropriate for use in equipment service, fluid power assemblies, and hydraulic line fabrication across both shop and field environments.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power system assembly practices. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fittings. NPTF threads are designed to seal on the thread form itself; inspect threads for damage before assembly and apply appropriate thread preparation as required by system specifications. Verify hose and fitting size compatibility before finalizing the assembly.
