Parker 2GF-4 Copper Flared Tube Gasket 1/4 in Od 45 Deg

Product Description

The PARKER 2GF-4 is a copper flared tube gasket designed to seal 45-degree flare connections on 1/4-inch OD tubing. It seats between mating flare fittings to create a leak-free metal-to-metal seal in refrigeration, HVAC, and hydraulic line assemblies. Rated to 1400 psi maximum working pressure and 250 degrees F maximum working temperature, this gasket handles demanding service conditions without deforming or extruding. The copper material conforms readily to flare seats, compensating for minor surface irregularities. HVAC technicians and refrigeration mechanics commonly use this gasket during line set installation, flare joint service, and system leak repairs.

This gasket is suited for residential and light commercial HVAC systems, refrigeration equipment, and hydraulic tubing assemblies that use 45-degree SAE flare connections on 1/4-inch OD copper or compatible tubing. It meets SAE J512 and SAE J513 dimensional standards and carries a UL Listing, making it appropriate for installations requiring listed components. It is typically installed wherever a reusable or replacement flare seal is needed at a 1/4-inch flare joint.

Compatibility

Designed as an OEM-style replacement gasket for 45-degree SAE flare connections on 1/4-inch OD tubing in refrigeration, HVAC, and hydraulic line applications conforming to SAE J512 and SAE J513.

Installation Notes

Licensed HVAC technicians and refrigeration mechanics should recover all refrigerant and depressurize the system before disassembling any flare joint. Inspect the flare seat on both the tubing and fitting for scoring or damage before installing a new gasket. Hand-tighten the flare nut to seat the gasket, then apply final torque with a properly sized flare nut wrench — do not overtighten, as copper gaskets can deform and leak if over-compressed. Follow applicable mechanical codes and the equipment manufacturer's service procedures for flare joint assembly.
