▶ Adapter OD Reference (For Custom & Off-Label Use)
This reference is intended for customers matching an existing hose or building a custom configuration.
If you are using a listed Adapter Kit, you do NOT need this chart.
Adapter OD Reference
| Adapter Type | Nominal Size | Adapter OD |
|---|---|---|
| Clamp Adapter | 3″ | 2.98″ |
| Clamp Adapter | 4″ | 3.875″ |
| Screw-Connect Adapter (ZY.Hyisinn) | 5″ | 4.93″ |
| QC Adapter (EcoFlow) | 5″ | 5.30″ |
| Clamp Adapter | 5.5″ | 5.45″ |
| QC Adapter (EcoFlow) | 6″ | 6.20″ |
Adapter OD values are intentionally slightly undersized to allow hose fitment.
Clamp-on and slip-fit adapters are typically ~0.05–0.15″ smaller than nominal hose size.
EcoFlow QC adapters taper past the retention ring and are designed for quick-connect couplers.
Clamp fitment may be limited.
