Bits Power Question

[gerico]

Can any of the bits power fiitings sold at OCUK be used with acrylic tubing?

They look so lush but not sure if I can use them alongside acrylic!

Is there away you can tell if they are work for rigid tubing? I find a lot of sites don't really give much description of the product
