Parker 6-8 Ctx-s Steel Flared Tube Male Elbow 3/8 in Od

Product Description

The PARKER 6-8 CTX-S is a 90-degree male elbow fitting designed for flared tube connections in hydraulic and fluid-system applications. Constructed from steel, it features a 37-degree flare seat on one end and a male NPTF thread on the other, providing a pressure-rated, leak-resistant joint. With a maximum working pressure of 6000 psi and a maximum working temperature of 500 degrees F, this fitting is suited for demanding service conditions. The 3/8-inch tube OD and 1/2-inch NPTF thread make it a compact, reliable directional connector for routing lines around obstructions in tight installations.

This fitting is used in hydraulic systems, pneumatic lines, and fluid-transfer assemblies found in industrial, mobile equipment, and HVAC/refrigeration piping applications. The 90-degree elbow configuration allows a clean directional change from a flared tube to a threaded port without field fabrication. It is typically installed by pipefitters, hydraulic technicians, and HVAC mechanics building or repairing fluid-line assemblies that require a secure, reusable mechanical joint.

Key Features

• 90-degree male elbow with 37-degree flare seat conforming to SAE J514 and ISO 8434-2
• Steel construction for strength and compatibility with hydraulic and petroleum-based fluids
• Maximum working pressure of 6000 psi for high-pressure line service
• Rated to 500 degrees F, suitable for elevated-temperature environments
• Flare x MNPTF end configuration transitions a flared tube to a standard NPTF threaded port
• Complies with SAE 070202, SAE J514, and ISO 8434-2 standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid-transfer systems requiring a 3/8-inch OD flared tube connection to a 1/2-inch male NPTF port.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or HVAC mechanic. De-pressurize and isolate the system completely before removing or installing any fittings. Ensure the mating tube end is properly flared to the 37-degree SAE specification before assembly; an improperly flared seat will compromise the pressure rating. Follow applicable NPTF thread engagement practices per ASME and SAE guidelines, and inspect for leaks before returning the system to service.
