Second batch of this tubing that I've bought because I liked the first so well.  I use it with my pumps and home brewery kettles.  The thicker 7/8" OD was definitely worth the price although I ended up getting a bit more than I need - better to go long than vice versa with this product.  Exactly what it says - it is a high-quality product.  It handles very hot (up to boiling/brewery temperatures) without degrading in shape or firmness.  It can be hot to the touch - gloves are a good idea when using it with hot liquids.
