Parker 712135 Steel Flared Tube Connector 3/8 in 37 Degree

Product Description

The PARKER 712135 is a steel flared tube connector designed for high-pressure hydraulic and fluid power applications. It features a 37-degree flare on one end and an O-ring boss (ORB) thread on the other, creating a reliable Flare x ORB connection. The connector accepts a 3/8 inch tube OD and uses a 7/8-14 thread. Rated to 5000 psi maximum working pressure and capable of handling temperatures up to 500 degrees F, this fitting is built for demanding service in industrial, mobile hydraulic, and fluid transfer systems. Licensed plumbers, pipefitters, and hydraulic system technicians are the typical installers.

This connector is suited for residential and commercial fluid power circuits, hydraulic lines, and related tubing assemblies where a transition between a 37-degree flare tube end and an ORB port is required. It is commonly installed in hydraulic manifolds, pump ports, valve bodies, and other components with straight-thread ORB ports. The 37-degree flare end conforms to SAE J514 standards, making it a direct-fit option for tubing assemblies built to that specification.

Key Features

• 37-degree flare end conforms to SAE J514 and ISO 8434-2 standards
• O-ring boss (ORB) thread end provides leak-resistant straight-thread port connection
• Rated to 5000 psi maximum working pressure, static and dynamic
• Handles temperatures up to 500 degrees F (260 degrees C)
• Steel construction for durability in high-pressure fluid service
• Overall length of 1.5 inches for compact installation clearances

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power tubing assemblies requiring a 37-degree flare to ORB transition with a 3/8 inch tube OD and 7/8-14 thread size, per SAE J514 and ISO 8434-2 specifications.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed tradesperson familiar with high-pressure fluid systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the flare seat and ORB port for damage or debris before assembly, and verify the O-ring is properly seated to prevent leaks. Applicable standards including SAE J514 and ISO 8434-2 should be followed for proper assembly torque and tube preparation procedures.
