Parker 10391 Steel Swivel Run Tee 5/16 in Od 37 Degree Flare

Product Description

The PARKER 10391 is a steel flared tube swivel run tee designed for hydraulic fluid and gas handling connection applications. This fitting features a 37-degree flare angle with flare x flare x flare end connections on all three ports. The swivel design allows for rotational adjustment during assembly, reducing the need to torque the mating line into a fixed position. With a maximum working pressure of 6000 psi, the 10391 is built for demanding hydraulic service. Plumbers, pipefitters, and hydraulic system technicians install this fitting in tubing runs where a branch connection is required without sacrificing pressure integrity.

The PARKER 10391 is suited for hydraulic fluid and gas handling systems that use 5/16 inch OD tubing with 37-degree flared ends. The run tee configuration allows the main tube run to continue straight through while a branch port diverts flow at a perpendicular angle. This fitting is commonly used in industrial hydraulic circuits, mobile equipment fluid lines, and high-pressure gas handling assemblies where steel construction and a 37-degree JIC-style flare are specified by the system design.

Key Features

• Steel construction rated for up to 6000 psi maximum working pressure
• 37-degree flare angle on all three ports for leak-resistant tube connections
• Swivel design permits rotational alignment during installation without twisting the tube
• Flare x flare x flare end connections compatible with standard 37-degree flared tube assemblies
• 5/16 inch tube OD sizing for use in smaller-diameter hydraulic and gas lines
• Sold in a package quantity of 5 units

Compatibility

Designed for use with hydraulic fluid and gas handling connections requiring 5/16 inch OD tubing and a 37-degree flare end configuration. Verify system pressure ratings and tube OD before installation.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber familiar with high-pressure tube fitting assemblies. Depressurize and isolate the hydraulic or gas circuit completely before disassembling any existing fittings or installing the new tee. Inspect flare seats on both the fitting and the mating tube ends for nicks or deformation before assembly, as surface defects can compromise the seal at high pressure. Torque to the fitting manufacturer specification for the tube OD and material — do not over-torque swivel nuts, as this can damage the flare seat.
