What to look for when choosing couplers & connectors
✔ Thread size & type – match hose and tool threads for a leak-free connection.
✔ Flow rating – Hi-Flo fittings improve performance on high-demand tools.
✔ Safety features – some couplers include automatic shut-off to prevent accidental air loss.
Quick tips:
For general workshop use, 1/4″ BSP options are most common.
In automotive or industrial settings, choose Hi-Flo or safety-rated couplers.
Ensure plugs and couplers are from reputable brands to reduce leaks and wear over time.
