Rigid Acrylic Tubing, Clear (Various Diameters and Lengths)
This is a thin walled (only 0.020″ to 0.030″ thick), rigid tubing. Sold in 12″, 24″ or 36″ lengths. Made from clear acrylic plastic.
Note the listed size is for the outside diameter, as these are intended to insert into clear vinyl tubing with the matchin inside diameter. i.e. use 3/16" O.D. acrylic tubing with 3/16" I.D. clear vinyl tubing.
