[100% Heavy Duty 304 Stainless Steel] These clamps are made of 100% 304 stainless steel, which is corrosion-resistant, rust-proof, and waterproof. They can be used in complex environments. The strong and sturdy material ensures that the adjustable hose clamps can be used for a long time. You no longer have to worry about them rusting and breaking. [360° SEALING PROTECTION] Allows strong thermal expansion compensation for dimensional changes caused by hose replacement, keeping the hose well sealed and watertight at all times. There are no steps or gaps in the hose clamp, and the inner circumference ensures uniform compression of the pipe surface, making the clamping effect significantly stronger than traditional screw-type hose clamps.
