RaceFlux Hose Barb Reducer / Expander Fitting

Join two hose sizes barb to barb: this reducer/expander carries a different barb size on each end, stepping rubber hose up or down mid-line without any threaded fittings — the quick fix when a component's hose stub doesn't match the line you're running.

Key Features

• Hose barb reducer/expander — two barb sizes in one fitting
• Steps rubber hose up or down without threaded connections
• Reusable

Fitment & Compatibility

• Combinations: 3/8" x 1/2" and 1/2" x 5/8" — select from the dropdown
