I had to order 10 feet of food grade silicone tubing for my DIY water filter. I only used 4 ft, so I have 6 ft leftover for someone else. 3/8th OD-- 1/4 ID I could not find this in many places and had to order from overseas, so it took about 3 weeks to get here. I can ship yours out as soon as the check clears. $12 shipped.
