BUY 2 GET 1 FREE!!! We have for sale, a solid rubber gasket or seal type rubber o-ring. This measures approximatly 15 feet long and they are in a loop, like a giant o-ring and .375" or 3/8" in diameter. These came in a storage unit that we won at auction. The only information that we have on these is the tag on the box. I tryed finding information online but could not come up with an application for the part number. The info on the tag was P/N: PPVV148 SIL SEAL SDB AUR REV. C .375" C/S SOLID ROD I did get an email from a buyer of one of these that said these o-rings are used on big equipment tires to seal the rubber tire to the steel rim around the bead. If you have any other questions, feel free to email me. Thanks BUY 2 GET 1 FREE!!!!
