Say goodbye to blown - off couplers! These spring - loaded 300 Series Stainless Steel bands offer a consistent clamping force even through heat cycles. Size ranges from 3.56 - 3.91'. Part Number: 1405212.

Using this hose clamp is easy. First, find the right position for the clamp on the hose and the coupler. Then, tighten the clamp securely. Make sure it's not too loose to prevent coupler blow - off, but don't overtighten as it might damage the hose. When it comes to maintenance, keep it clean. If it's exposed to a lot of moisture, dry it off to avoid rust. Check the clamping force regularly, especially after going through heat cycles. If you notice any signs of wear or if the clamping force isn't consistent, it might be time to replace the clamp.
