Black Plastic Air tubing? It can be used in construction, It gets filled with pesticide, and/or termite killer/repeller, something. Anyway, It's just plastic before the filled with the pesticide, and It's the same size(Inside) as air tubing, overall, it's a little thinner, but less maluable(sp?) Because it's plastic. I was wondering if anyone had ever used something like this for they're tanks?
