Parker 12 Ctx-s Steel Flared Tube Male Elbow 3/4 in

Product Description

The PARKER 12 CTX-S is a 90-degree male elbow fitting designed for flared tube connections in high-pressure hydraulic and pneumatic systems. Machined from steel, it connects a 37-degree flared tube to a male NPTF threaded port, providing a leak-resistant mechanical seal without sealant tape when properly assembled. The fitting handles a maximum working pressure of 4000 psi and a maximum temperature of 500 degrees F, making it suitable for demanding fluid power and industrial plumbing applications. Licensed plumbers, hydraulic system technicians, and industrial pipefitters routinely install this fitting type when routing tube lines through tight directional changes.

This fitting is used in fluid power systems, hydraulic circuits, and industrial plumbing installations where a 3/4 inch OD tube must transition to a 3/4 inch NPTF threaded port at a 90-degree angle. The 37-degree flare angle conforms to SAE J514 and ISO 8434-2, making it compatible with standard SAE 37-degree flared tube assemblies found in mobile equipment, machine tools, and process piping. Its steel construction supports use in oil, air, and many fluid media lines operating within rated temperature and pressure limits.

Key Features

• 90-degree elbow orientation for routing tube lines through directional changes in tight spaces
• 37-degree flare angle per SAE J514 and ISO 8434-2 for standardized compatibility
• Flare x MNPTF end connections for direct tube-to-port assembly
• Rated to 4000 psi maximum working pressure for high-pressure hydraulic and pneumatic service
• Maximum service temperature of 500 degrees F (260 degrees C)
• Steel construction for durability in industrial and mobile equipment environments

Compatibility

Designed for use with 3/4 inch OD, 37-degree SAE flared tube assemblies terminating at a 3/4 inch NPTF male threaded port. Conforms to SAE 070202, SAE J514, and ISO 8434-2 standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician, pipefitter, or licensed plumber familiar with SAE flared tube fittings and NPTF threaded connections. Depressurize and drain the system completely before removing or installing any fitting. Inspect the tube flare and fitting seat for nicks, burrs, or deformation before assembly, as surface defects cause leaks under pressure. NPTF threads are designed to seal on the threads themselves; follow applicable industry standards for thread engagement and assembly procedure.
