its specific to the VW jug. fwiw the VW jugs are less expensive than the other adblue stuff around here

On accident, I found the same as well. 2.5 gal jug for $8.75. I'm definitely buying this hose. I bought one of the small bottles and cut the bottom of if to use as an adapter. This hose will make it a quicker/easier process.
