The ear clamp works by deforming a single ear section when crimped, applying uniform 360-degree compression around the hose. With a 1-5\/8-inch nominal size, 7 mm band width, and 0.6 mm band thickness, this clamp provides a low-profile, vibration-resistant seal. Constructed from stainless steel, it resists corrosion in wet, chemical-exposed, and outdoor environments. HVAC technicians, plumbers, and refrigeration mechanics install these clamps where worm-gear or spring clamps are not acceptable and a tamper-evident, leak-free connection is required.\u003c\/p\u003e\u003cp\u003eEar clamps in this size range are commonly used on heater hose connections, coolant bypass lines, PEX tubing fittings, low-pressure pneumatic lines, and flexible duct collars. The 1-5\/8-inch nominal diameter suits a wide range of standard hose and tubing found in residential and light commercial HVAC systems, plumbing rough-in work, and hydronic heating installations. These clamps are installed using a dedicated ear clamp pincer tool or compatible crimping pliers and are not intended for repositioning after crimping.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-5\/8-inch nominal clamp size for precise fitment on standard hose and tubing\u003c\/li\u003e\n\u003cli\u003eSingle-ear design provides uniform 360-degree compression when crimped\u003c\/li\u003e\n\u003cli\u003eStainless steel construction resists corrosion in wet and chemically exposed environments\u003c\/li\u003e\n\u003cli\u003e7 mm band width and 0.6 mm band thickness for a low-profile installation footprint\u003c\/li\u003e\n\u003cli\u003e10 mm inner ear width supports consistent crimp engagement with standard pincer tooling\u003c\/li\u003e\n\u003cli\u003ePermanent, tamper-evident seal once installed — not reusable after crimping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation ear clamp for standard 1-5\/8-inch hose and tubing connections in HVAC, plumbing, and hydronic systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a dedicated ear clamp pincer tool or calibrated crimping pliers rated for the clamp ear width — do not use slip-joint or tongue-and-groove pliers as a substitute. Shut off fluid flow and depressurize the line before installing or inspecting clamps on pressurized systems. Once crimped, the clamp is permanently deformed and must be cut off for removal — plan for single-use application. Follow applicable plumbing and mechanical codes, including IPC and IMC guidelines, for hose connection requirements in the system being serviced.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Type\u003c\/strong\u003e: Ear Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand Width\u003c\/strong\u003e: 7 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand Thickness\u003c\/strong\u003e: 0.6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Width of Ear\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OETIKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16705989-100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OETIKER","offers":[{"title":"Default Title","offer_id":51542817603890,"sku":"16705989-100","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be09fb1fbcbfd972256e1fb7d5ef4fc6.jpg?v=1785908242","url":"https:\/\/voomisupply.com\/products\/oetiker-16705989-100-ear-clamp-1-5-8-in-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
