Parker 6-4 Trtx-s Steel Flared Tube Reducer 3/8 X 1/4 in

Product Description

The PARKER 6-4 TRTX-S is a steel flared tube reducer fitting designed to connect tubing of two different outside diameters within a hydraulic or fluid system. It transitions from a 3/8 inch OD tube on the female flare end to a 1/4 inch OD tube on the male flare end, using a 37-degree flare angle on both connections. Rated to a maximum working pressure of 6000 psi and a maximum working temperature of 500 degrees F, this fitting is built for demanding industrial and fluid power applications. Licensed plumbers, hydraulic technicians, and fluid system mechanics are the primary installers of this component.

This reducer is suited for use in hydraulic lines, fluid power circuits, refrigeration tubing assemblies, and other high-pressure tubing systems where a step-down connection between two tube sizes is required. The 37-degree flare design conforms to SAE J514 and ISO 8434-2 standards, making it compatible with systems built to those specifications. It is appropriate for both stationary and mobile equipment where steel fittings are specified.

Key Features

• Reduces from 3/8 inch to 1/4 inch tube OD in a single fitting
• 37-degree flare angle on both ends per SAE J514 and ISO 8434-2
• 6000 psi maximum dynamic working pressure
• Rated to 500 degrees F maximum working temperature
• Steel construction for durability in high-pressure fluid systems
• Overall length of 1.4 inches for compact inline installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for hydraulic and fluid power systems requiring a 37-degree flared tube reducer conforming to SAE J514 and ISO 8434-2 standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with flared tube fittings and applicable fluid system codes. Depressurize and isolate the hydraulic or fluid circuit completely before removing or installing any fittings. Inspect both flare seats for damage or contamination before assembly, and do not overtighten, as this can deform the flare and cause leaks. Consult SAE J514 torque and assembly guidelines for proper makeup procedures.
