The size standard has no deviation, meeting daily needs for products of different sizes. 304 Stainless Steel Hose ClampsThe large duct clamps are all constructed from heavy-duty 304 stainless steel (including steel strips, housing, and screws), a strong and durable material. Even in harsh environmental conditions, they provide excellent corrosion and rust resistance, ensuring long-lasting use.

Powerful Tightening CapabilityTo eliminate concerns about break out and strip out, these stainless hose clamps are designed with a reinforced and widened steel band, featuring through-hole manufacturing craftsmanship, a precise polished surface without burrs, and large torque that tightly locks and fixes hoses to effectively prevent pipeline leakage issues without causing any damage to the hose. Not Backed Out ScrewThe sturdy stainless steel fasteners use a worm gear spiral mechanism to allow the metal strip to pass smoothly and secure it more quickly. By deepening and improving the thread, the screws will not loosen, slip, or fall out, thereby increasing the stability of the product.
