10' of flexible supply tubing. 1/4" outside diameter.
Flexible supply tubing that connects the AquaPurr to the diverter valve on the faucet.
At the end of 2021 I began a transition to new tubing made by Hudson Extrusions. The pressure rating is very high at 205 PSI and is NSF 51 / 61 rated which means it is meant for drinking water.
This is the same sort of tubing you would see for supplying water to refrigerators for ice makers and water dispensers.
