PARTS UNLIMITED Standard Inner Tube — 8", 3.50-8, 4.00-8, Center Metal Valve 90° Bend

🔧 Dependable standard inner tube built for longer air retention and simple service.

• “Real butyl tubes” made from 100% butyl polymer, not a blend, to minimize natural air leakage.
• Individually boxed: each tube is packaged separately with size and valve stem type clearly marked on the box end for fast identification.
• 100% butyl construction helps maintain pressure longer than blended tubes, reducing the need for frequent top-offs.

Whether replacing a worn tube or stocking parts for routine maintenance, these tubes offer consistent sealing and reliable performance. ⏱️
