I have been getting TPE [thermoplastic elastomer] hose of up to
1" inside diameter from MSC industrial supply.  For some reason
they don't stock anything larger.

Does anyone have a source for TPE hose in 1-1/4" or 1-1/2" diameter
or a suitable substitute for tubing a player piano?

I went back to the auto parts store today and the 1-1/2" radiator
hose I had been using now costs $30 per foot.  :-0
