Flat Free Sealant Filled 4 In. Hand Truck Tire Inner Tube

Quick-Seal tubes come pre-filled with Flat Free Tire Sealant. The sealant's synthetic fibers, adhesion agents, and corrosion inhibitors work inside the tube to find and seal punctures as large as 1/8-inch as soon as they occur. The Quick-Seal tubes provide standard inner tube maintenance along with continuous protection against future flats.
