Parker 48F-6-12 Brass Flared Tube Connector 3/8 in Od

Product Description

The PARKER 48F-6-12 is a brass flared tube connector designed for use in hydraulic, pneumatic, refrigeration, and fluid-transfer systems where a leak-free flared connection is required. It features a 45-degree flare seat on the tube end and a male NPTF (Dryseal) threaded end on the port side, creating a reliable metal-to-metal seal without sealant tape under normal conditions. The connector accepts 3/8 inch OD tubing and threads into a 3/4-14 NPTF port. Rated to 1000 psi maximum working pressure and 250 degrees F, it is suited for demanding service environments. Licensed plumbers, HVAC technicians, and pipefitters install this fitting in both residential and commercial applications.

This connector is commonly used in refrigeration line sets, fuel systems, hydraulic circuits, and compressed-air plumbing where 45-degree SAE flare connections mate to NPTF-threaded ports. The Flare x MNPTF configuration makes it a transition fitting between flared tubing and pipe-threaded components. It is appropriate for use with copper, aluminum, and steel tubing that meets SAE J512 and SAE J513 flaring specifications. At 1.79 inches overall length and 0.2 pounds, it is compact enough for tight equipment installations.

Key Features

• 45-degree SAE flare seat conforms to SAE J512 and SAE J513 standards
• Dryseal NPTF male thread provides a pressure-tight connection at the port end
• 1000 psi maximum working pressure for demanding fluid and gas service
• 250 degrees F maximum working temperature rating
• Full brass construction resists corrosion in refrigerant, fuel, and water service
• UL Listed for added compliance assurance

Compatibility

Designed for use with 3/8 inch OD tubing flared to 45-degree SAE specifications, threading into 3/4-14 NPTF ports. Conforms to SAE J512, SAE J513, and NPTF Dryseal thread standards.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician familiar with flared tube fittings and NPTF threaded connections. Shut off and depressurize the system completely before disassembly or installation. Ensure the tube end is cleanly cut, deburred, and properly flared to a 45-degree angle before seating against the fitting flare cone. NPTF dryseal threads are designed to seal on thread engagement alone, but verify system requirements before deciding whether to apply thread sealant.
