Spring Tension Clamps for 3mm, 5mm, or 6mm ID vacuum hose (10-PACK)

Self-tensioning spring band clamps that provide a leak-free seal by adapting to the expansion and contractions of hoses that are subject to fluctuating temperatures within engine compartments.  A good fastener for your silicone vacuum hose needs.  Ideally, you do not need clamps like these when your vacuum hose is properly fitted to the fitting that it is attached to... tension should do its job and hold the hose securely.  But if your hose is just a little too large in diameter, or if you like to have fail-safes on all your projects, these just might be for you.  As per the manufacturer, choose the size of spring tension clamp that matches the Internal Diameter of the vacuum hose.  Pack of 10.
