Replacement Tubing for the Neptune DOS Dosing and Fluid Metering System
If you need longer tubing for your DOS dosing system or DDR reservoirs. Extend the distance from your pump to the reservoirs, or the pump to your tank.
Two Sizes Available:
- 4 Meters
- 16 Meters
Unfortunately the Bulkhead tank adapter will require firm Polyethylene tubing which the DOS tubing will not work with. You may be able to try 1/4" RO tubing to attach the to DOS however this will not be a guaranteed fit.
