Jolinator, try sending an Email to DangerDen. They sell the McMaster silicon hose in 1/8" wall thickness. I'd have to assume that at least one of there customers have used die-lite. In my oppinion however theres no reason silicon should shield UV, although it won't be as bright as vinyl as it's milky... so less UV in equals less light produced... equals less light out threw tube again.
Did you need any info on hose clamps?
