Inner Tube B20023 - Standard - 15" - PV-78 - 90° Center Metal Valve

"Real butyl tubes" made from 100% butyl polymer, unlike other "butyl" tubes, which are blended with butyl polymer and natural rubber. Each tube is individually boxed with a full range of sizes and valve stem types clearly marked on each box end. 100% butyl tube minimizes natural air leakage while maintaining air pressure for a longer period of time.
