Parker 179C-6-4 Male 45 Elbow Compression X Mnpt Brass

Product Description

The PARKER 179C-6-4 is a brass male 45-degree elbow fitting designed for compression tube-to-pipe connections in fluid and pneumatic systems. It connects a compression tube end to a male NPTF threaded port at a 45-degree angle, redirecting line runs in tight installations. Thread size is 1/4-18 NPTF, and the fitting is rated for a maximum working pressure of 200 psi with an operating temperature range of -65 degrees F to 250 degrees F. Manufactured to SAE J-512 standards, it delivers consistent sealing performance in both hydraulic and pneumatic plumbing applications. Plumbers, HVAC technicians, and industrial pipefitters install this fitting where angled tube routing is required.

This fitting is suited for residential and light commercial plumbing, HVAC refrigerant line accessories, and industrial fluid-handling systems where a compression tube must transition to a male NPT threaded port at a 45-degree offset. It is typically used in copper or compatible soft-metal tubing assemblies. The 1/4-18 NPTF thread ensures a pressure-tight connection without relying on thread sealant tape alone, making it appropriate for systems that must meet SAE J-512 requirements.

Key Features

• 45-degree male elbow configuration for angled tube-to-pipe routing
• Compression x MNPT end connections for secure, leak-resistant joints
• Brass construction for corrosion resistance and compatibility with a wide range of fluids
• Rated to 200 psi maximum working pressure
• Operating temperature range from -65 degrees F to 250 degrees F
• Manufactured to SAE J-512 standard

Compatibility

Designed as an OEM-style replacement or new-install compression fitting for systems using 1/4-18 NPTF male port connections with compression tube ends, per SAE J-512.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter. Shut off and depressurize the system completely before removing or installing any fittings. Ensure tube ends are cut cleanly and deburred before seating into the compression ferrule to achieve a proper seal. Follow applicable codes including IFGC or IPC as appropriate to the system type.
