About this item

These 1/2 inch OD copper flare tube fittings come as a pair and are listed for refrigeration and plumbing. The size is given as 12.7mm outside diameter, which is how refrigeration and soft copper tube are measured, not nominal pipe size.

How does a copper flare fitting seal?

You flare the tube end with a flaring tool. The flare nut then pulls it tight against the fitting's cone, which makes a metal-to-metal seal without heat.

• Fitting type: check the listing photos to see whether these are unions, nuts or adapters.
• Flare angle: make sure it matches your tool and mating parts.
• Quantity: 2 pieces.
• Refrigerant work: may require certification, and gas lines need code-approved methods and permits.
