Brass SAE 45° Flare Reducing Union — Male Flare × Male Flare
The Brass SAE 45° Flare Reducing Union joins two flared tube runs of different sizes in a single fitting, with a male SAE 45° flare on each end. The 45° flare seat forms a reliable metal-to-metal seal on flared copper, brass, aluminum, or soft steel tubing — no sealant required — making it a go-to adapter whenever a line needs to step up or down between tube sizes.
Machined from CA360 brass barstock with a wrench-flat hex body for easy, controlled tightening.
