Parker 4-4 Ctx-s Steel 90 Deg Male Elbow 1/4 in Tube Od

Product Description

The PARKER 4-4 CTX-S is a 90-degree male elbow fitting designed for flared tube connections in high-pressure hydraulic and fluid system applications. Constructed from steel, it features a 37-degree flare seat on the tube end and a male NPTF thread on the pipe end, providing a leak-resistant mechanical seal without the need for additional sealant when mated to a properly flared tube and NPTF port. Rated to 6000 psi maximum dynamic working pressure and capable of handling temperatures up to 500 degrees F, this fitting is built for demanding service environments where reliability under pressure is critical. It weighs 0.01 pounds.

This fitting is used in hydraulic lines, pneumatic systems, refrigeration circuits, and other fluid-handling installations where a 90-degree direction change is required between a flared tube and a male NPTF port. It is well-suited for both industrial and mobile equipment applications. The 1/4-inch tube OD and 1/4-inch thread size make it a common choice for smaller-diameter tubing runs in tight routing situations. Installation is typically performed by a hydraulic technician, plumber, or HVAC-R mechanic during system assembly or repair.

Key Features

• 90-degree male elbow configuration for direction changes in tube routing
• 37-degree flare seat conforms to SAE J514 and ISO 8434-2 standards
• Steel construction rated to 6000 psi maximum dynamic working pressure
• Temperature range up to 500 degrees F (260 degrees C)
• Flare x MNPTF end connections for leak-resistant sealing at both ends
• Meets SAE 070202, SAE J514, and ISO 8434-2 standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4-inch OD flared tubing with a 37-degree flare angle mating to a 1/4-inch NPTF threaded port.

Installation Notes

Shut down the system and relieve all pressure before removing or installing any hydraulic or fluid fittings. Ensure the mating tube is properly flared to a 37-degree angle using calibrated flaring tooling before tightening. Inspect the flare seat and NPTF threads for damage or contamination prior to assembly. NPTF threads are designed to seal on thread engagement, but verify torque and leak-free status per the applicable system pressure requirements and relevant SAE or IFGC guidelines.
