Flare fittings are used on soft copper tubing for applications with water, oil, or gas.
Fittings, except caps and unions, are all male flare and require a short flare nut, sold separately, to make a connection.
These fittings are NOT lead free and may not be used in potable water systems.
All flare sizes are listed as OD (outside diameter) of the tubing they fit. See chart for OD to ID comparison.
