This listing consists of a set of five clear premix fountain valve shanks and O rings. They are new old stock. They are 3 5/8 inches long. The smaller end is threaded. These would be great for anyone doing refurbishing a vintage Coca-Cola fountain. I offer speedy shipping and combined shipping with the purchase of more than one item. If you purchase more than one item please don’t pay until I can send you a invoice with the shipping cost adjusted to save on shipping cost.
