Parker 48F-5-2 Brass Flared Tube Connector 5/16 in Od

Product Description

The PARKER 48F-5-2 is a brass flared tube connector designed for use in fluid and refrigerant line assemblies where a leak-free, pressure-rated mechanical connection is required. It features a 45-degree flare on one end and a male NPTF threaded end on the other, joining a 5/16 inch OD flared tube to a 1/8-27 NPTF port. Rated to 1200 psi maximum working pressure and 250 degrees F maximum working temperature, this connector is suited for systems where both pressure integrity and thermal resistance matter. HVAC technicians, plumbers, and refrigeration mechanics install this fitting as part of copper or compatible tubing runs in both residential and light commercial applications.

This connector is used wherever a flared tube must terminate into a threaded port on a valve, manifold, or component body. Common applications include refrigeration lines, hydraulic circuits, fuel systems, and compressed-air plumbing. The 45-degree flare angle conforms to SAE J512 and SAE J513 standards, making it compatible with standard SAE 45-degree flare tooling and fittings found throughout HVAC, refrigeration, and general fluid-handling trade work. The NPTF thread provides a dry-seal connection that does not rely solely on thread sealant for pressure integrity.

Key Features

• 45-degree flare end conforms to SAE J512 and SAE J513 standards
• Male NPTF (dry-seal) thread eliminates dependence on sealant alone for pressure integrity
• 1200 psi maximum working pressure rating for demanding fluid and refrigerant service
• 250 degrees F maximum working temperature suitable for a wide range of system operating conditions
• Brass construction provides corrosion resistance and compatibility with common refrigerants and hydraulic fluids
• UL Listed fitting meeting recognized industry safety standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 5/16 inch OD flared tubing and 1/8-27 NPTF threaded ports in HVAC, refrigeration, hydraulic, and general fluid-handling applications.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or qualified mechanic. Depressurize and isolate the system before removing or installing any fitting. Use proper SAE 45-degree flaring tools to prepare the tube end; an improperly flared tube will not seal reliably regardless of torque. Do not over-torque the NPTF threads — hand-tighten plus a measured number of turns per standard practice, and inspect for leaks after returning the system to pressure.
