3/4" Two-Ear Hose Clamp – 17/20 Size Equivalent Our heavy-duty 3/4" two-ear hose clamps are a direct size equivalent to the 17–20 mm clamp range commonly referenced in Oetiker-style fittings (such as Oetiker 15100010 size classification). These are not branded Oetiker clamps, but are compatible replacements in size and application. Built from high-quality zinc plated carbon steel, these clamps are designed for demanding air and fluid line applications where strength, reliability, and long-term sealing performance matter. Unlike thin, low-grade alternatives, these clamps are manufactured for heavy-duty use in industrial, automotive, and shop environments. The two-ear design provides consistent, uniform compression around the hose, creating a secure, leak-resistant, and tamper-resistant seal once installed. After crimping, the clamp becomes permanent and vibration-resistant, making it ideal for systems where failure or loosening is not an option. Smooth, rounded edges help prevent hose damage during installation and operation, reducing the risk of cuts or premature wear. Professional Installation Standard Two-ear clamps are widely used in OEM, industrial, and professional compressed air and fluid systems where a permanent, vibration-resistant connection is required. Compared to traditional worm gear clamps, two-ear clamps provide more uniform compression around the hose and are significantly more resistant to loosening over time due to vibration or thermal cycling. Worm gear clamps are adjustable and reusable, but in many permanent or high-vibration applications they can develop uneven pressure points or gradually loosen. Two-ear clamps are often the preferred choice when a secure, maintenance-free connection is required in professional environments.
