Radium Spring Hose Clamp — Single
Spring hose clamps are commonly used by OEM manufacturers in low-pressure applications such as PCV (positive crankcase ventilation) and coolant hoses. Unlike worm-drive clamps that dig into and permanently damage hose material, spring clamps feature a constant-tension spring-action band that automatically expands and contracts as hose temperature fluctuates — maintaining a consistent, leak-free seal throughout the full operating temperature range.
Radium spring hose clamps are made from steel with a zinc-plated finish for corrosion resistance. Available in six sizes to suit a wide range of hose diameters from 1/4" through 3/4".
Suits: Universal — PCV, coolant, and other low-pressure hose applications
