Parker 2GF-6 Copper Flared Tube Gasket 3/8 in 45 Degree

Product Description

The PARKER 2GF-6 is a copper flared tube gasket designed to seal 45-degree flare connections on 3/8-inch OD tubing. It provides a leak-free metal-to-metal seal at flare joints in refrigeration, HVAC, and fluid-handling systems. Rated to 1000 psi maximum working pressure and 250 degrees F maximum working temperature, this gasket meets SAE J512, SAE J513, and UL Listing standards. HVAC technicians and refrigeration mechanics install these gaskets during line set connections and service valve work where a reliable, code-compliant flare seal is required.

This gasket is suited for residential and light commercial HVAC systems, refrigeration equipment, and pneumatic or hydraulic lines that use standard 45-degree SAE flare fittings on 3/8-inch OD copper tubing. It is commonly used at service valves, flare unions, and flare adapter connections in systems that carry refrigerant, compressed air, or hydraulic fluid within its rated pressure and temperature range. The copper material conforms reliably to machined flare seats, maintaining a secure seal through normal system pressure cycling.

Key Features

• Copper construction conforms to flare seat surfaces for a leak-resistant metal-to-metal seal
• 45-degree flare angle matches standard SAE flare fittings on 3/8-inch OD tubing
• Rated to 1000 psi maximum working pressure for use in high-pressure refrigeration and fluid systems
• Maximum working temperature of 250 degrees F supports a wide range of HVAC and refrigeration applications
• Meets SAE J512, SAE J513, and carries UL Listing for code-compliant installations

Compatibility

Designed for use with standard 45-degree SAE flare fittings on 3/8-inch OD copper tubing in refrigeration, HVAC, and fluid-handling systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician or refrigeration mechanic. Always recover refrigerant and depressurize the system before disassembling flare connections. Seat the gasket squarely against the flare face before tightening the flare nut to avoid misalignment and leaks. Inspect the flare seat for nicks or damage before reuse, as surface defects can prevent a proper seal even with a new gasket.
