Brass Flare Fittings
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 at the bottom of the page for OD to ID comparison
O.D. [Outside Diameter] to I.D. [Inside Diameter] Tubing Size Conversion
|tubing o.d.||tubing i.d.|
Use 1/2" flare fittings
on 3/8" i.d. copper.
|For small sizes, i.d. plus 1/8" equals o.d..|
