Parker 149F-4-4 Brass 45 Deg Male Elbow 1/4 in Tube Od

Product Description

The PARKER 149F-4-4 is a brass 45-degree flared tube male elbow designed for use in refrigeration, HVAC, and fluid-system piping applications. It connects a 1/4-inch OD flared tube to a 1/4-18 NPTF male threaded port, providing a reliable, leak-resistant transition at a 45-degree angle. The fitting is rated to 1,400 psi working pressure and handles temperatures up to 250 degrees F, making it suitable for a wide range of refrigerant, fuel, and hydraulic line installations. HVAC technicians and plumbers install this fitting where angled routing is needed between tubing and threaded fittings on valves, manifolds, or equipment ports.

This elbow is suited for residential and light commercial HVAC systems, refrigeration equipment, and plumbing assemblies where a flared copper or aluminum tube must mate to a male NPT port at a 45-degree angle. It is commonly used in refrigerant line sets, fuel gas lines, and hydraulic circuits where space or routing constraints require an angled connection rather than a straight fitting. The compact brass construction resists corrosion in wet and refrigerant-exposed environments.

Key Features

• 45-degree flare-to-MNPTF configuration for angled tube-to-port connections
• Rated to 1,400 psi maximum working pressure for high-pressure line applications
• Temperature range up to 250 degrees F for refrigerant and fluid service
• 1/4-inch tube OD flare end mates to standard SAE flared tubing
• 1/4-18 NPTF thread provides a dry-seal connection without requiring thread sealant tape in most applications
• Meets SAE J512, SAE J513, and UL Listing standards

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/4-inch OD flared tubing with 1/4-18 NPTF male threaded ports, conforming to SAE J512 and SAE J513 flare standards.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber. De-pressurize and isolate the line before removing or installing any fitting. Ensure the flared tube end is properly flared to SAE specification before seating it against the fitting cone — an improperly flared tube will not seal at rated pressure. NPTF threads are designed for dry-seal engagement, but consult applicable IFGC or system manufacturer guidelines before deciding whether to use thread sealant on the male threads.
