Slime 4" SmartTube Self-Healing Utility Tube

Description

This 4" self-healing utility tube with pre-filled Slime Tire Sealant offers up to two years of flat-free use for yard wagons and wheelbarrows. The SmartTube Self-Healing Utility Tube uses Fibro-Seal Technology to instantly seal punctures up to 1/8", maintaining tire integrity with automatic sealant action.
