Need a reliable, simple way to secure hoses? This Fielect 100-pack of spring band clamps is perfect for DIYers and pros alike. Each clamp has a 12mm (0.47\) inner diameter and is made from durable 65Mn spring steel – they resist rust and corrosion, even in humid environments. The 360-degree inner ring design helps prevent damage to your pipes or hoses. These clamps are self-tensioning, so they provide a tight, leak-proof seal without constant adjusting. Use them on fuel lines, air hoses, water pipes, silicone vacuum tubes, machinery, or even firefighting equipment. They’re easy to slide on with your fingers, and you can use pliers to open them up. Just remember: the clamp's inner diameter should be slightly smaller than your hose’s outer diameter (about 8mm less). A versatile, heavy-duty set that’ll keep your connections secure.
