All Balls Racing – Hose & Clamp Kits - Universal, including Hose Clamp 4 Packs in 7.6mm, 8.3mm, 9mm, 12mm, 14.3mm, 15.2mm and 16.6mm sizes. These are the fasteners nobody thinks about until a fuel line weeps at the carb inlet, a coolant hose seeps at the water pump or a vent line pops off in a whoop section and leaves you stranded. The pinch-style clamps in these packs apply even pressure all the way around the hose instead of biting into it the way a worm-gear clamp does, which keeps soft fuel and vacuum lines from being cut through over time and keeps them sealed through heat cycles and vibration. Sizing by hose outside diameter is what makes them work, so buying in four packs across the sizes you actually run lets you build a small bin and finish jobs without a parts run in the middle of a rebuild. The bands resist corrosion in salt, mud and water. Riders rebuilding a carb, replacing coolant lines or plumbing a fuel pump use these motorcycle hose clamps for factory-tidy connections. Measure your hose OD, or tell us the machine and the line you are plumbing, and we will confirm the right hose clamp size before you order.
