Parker 1J943-16-16 Female Seal-lok Swivel Elbow 1 in

Product Description

The PARKER 1J943-16-16 is a Female Seal-Lok Swivel Elbow hydraulic hose fitting designed for high-pressure fluid conveyance systems. Built from steel with a threaded connection type, this fitting features a 90-degree elbow geometry and accepts hoses with a 1-inch inside diameter (Hose Size 16). The Seal-Lok interface uses a captive O-ring face seal to minimize leak paths at the connection point, making it suitable for demanding hydraulic circuits. It is installed by licensed hydraulic technicians and industrial mechanics working on mobile equipment, industrial machinery, and fluid power systems where reliable, low-leak fittings are required.

This fitting is rated for use with a wide range of Parker hydraulic hose series in size 16 (1-inch ID) configurations. It is commonly installed in applications where a 90-degree directional change is needed at the hose-to-port connection, reducing bend stress on the hose assembly. Typical install scenarios include mobile hydraulic systems, construction equipment, agricultural machinery, and industrial press circuits. The swivel design allows the fitting body to rotate during assembly, simplifying routing and reducing torsional stress on the hose.

Key Features

• 90-degree elbow geometry for directional routing in tight or angled installations
• Seal-Lok O-ring face seal interface reduces leak potential compared to tapered thread connections
• Swivel design allows body rotation during assembly for easier hose routing
• Steel construction for durability in high-pressure hydraulic environments
• Threaded connection type compatible with standard hydraulic port interfaces
• Meets ISO 12151-1 standards; note California PROP 65 requirements apply

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power system assembly practices. Depressurize and bleed the hydraulic system fully before removing or installing any fittings. Inspect the O-ring sealing face for damage or contamination prior to assembly, and use a compatible O-ring lubricant as appropriate. Refer to Parker assembly guidelines and applicable industry standards for proper fitting engagement and system pressure testing after installation.
