Parker 46F-6-6 Brass Flared Tube Connector 3/8 in Od

Product Description

The PARKER 46F-6-6 is a brass flared tube connector designed for use in hydraulic, pneumatic, refrigeration, and fluid-transfer lines. It features a 45-degree flare seat on the tube end and a female NPTF thread on the opposite end, creating a leak-resistant connection without the need for sealant tape on the threaded side. The connector accepts 3/8-inch OD tubing and uses a 3/8-18 thread size. Rated to 1000 psi maximum working pressure and 250 degrees F, it suits demanding service environments encountered by HVAC technicians, plumbers, and fluid-system mechanics.

This fitting is used where a flared copper, aluminum, or steel tube must transition to a female NPT port on a valve, manifold, compressor, or equipment housing. It is suited for residential and light commercial HVAC systems, refrigeration equipment, hydraulic lines, and general industrial plumbing applications. The SAE J512 and SAE J513 flare standards and UL Listing make it appropriate for code-sensitive installations. Sold individually, it is stocked for single-unit repair and maintenance work as well as larger service calls.

Key Features

• 45-degree flare seat conforms to SAE J512 and SAE J513 standards for reliable leak-free seals
• Female NPTF (Dryseal) thread eliminates the need for thread sealant under normal conditions
• Rated to 1000 psi maximum working pressure
• Rated to 250 degrees F maximum working temperature
• Solid brass construction resists corrosion in refrigerant, hydraulic fluid, and water service
• UL Listed — meets safety requirements for applicable installation environments

Compatibility

Designed as an OEM-style replacement or service fitting for any system using 3/8-inch OD flared tubing with a 3/8-18 NPTF female port connection, conforming to SAE J512 and SAE J513 flare specifications.

Installation Notes

Installation should be performed by a qualified HVAC technician, plumber, or pipefitter. Depressurize and isolate the line completely before removing any existing fitting. Ensure the tube end is cut cleanly, deburred, and flared to the correct 45-degree angle using a calibrated flaring tool before seating the connector. Torque to the fitting manufacturer and applicable SAE or system specifications — do not overtighten, as brass flare fittings are susceptible to seat damage from excessive force.
