Does this tygon stretch diameter wise as well as silicone? What I mean is will it stretch to one barb bigger than it's standard ID (3/8ID tygon --> 1/2ID barb)? I'm was going to order some 3/8ID silicone from dangerden because the 1/2ID is so large (I have 1/2" barbs), but tygon seems interesting, and I might try some just for fun. Not absorbing chemicals is a major plus, tho.
