Sani-tech clear plastic TC level gauge?

[gitchegumee]

Anyone know where to buy clear or semi-clear FDA plastic "tube grant" material? Used to be on DME mash/lauter tuns as a tube grant. It's 1 1/2 inch TC molded directly on the end of a 1 1/2 inch FDA plastic tube. Very handy for level indication on mash/lauter/whirlpool. I'd really appreciate any leads for a source. Thanks!
