where do you guy's get the poly site glass material from? is it online or does lowes or someone carry it? had the one that came on my keggle break.
McMaster Carr is probably your best source for polycarbonate tubing. I think the minimum order is 8 ft. which is still relatively cheap and gives you quite a bit of material.
i got mine with my weldless fitting kit. Might be able to call them up and order a piece. separate Mcmaster will charge you a lot for shipping to send a 8 foot length. http://weldlessfittings.com/spareparts.html replacement 19" tube is 5 bucks...4.95 flat rate shipping
