Couldn't load pickup availability
The Automatic Diluent Valve (RB70KIT) delivers diluent gas to your breathing circuit on demand — automatically supplying gas when negative pressure is detected in the inhale counterlung, or manually via the diaphragm cover. An essential upgrade for streamlined gas management on any AP rebreather.
Key Features
- Upstream tilt valve design — eliminates free-flow risk from a leaking first stage seat
- 300-degree swivel accommodates front-feed routing from side-mounted diluent cylinders
- No adjustment or free-flow cut-off device required
- Includes C Spanner and 15" ADV hose (AP300/15, can be shortened)
| Part Number | RB70KIT |
| Compatibility | All AP Diving rebreathers (fits in place of inhale T-piece) |
| LP Hose Thread | 3/8" UNF (connects to 7–11 bar LP port) |
| Swivel Thread | 9/16" UNF female regulator connector |
Longer hose options (e.g., AP300/38 at 38"/97cm for first stage connection) are available on request.
