The clamp features a 3.25-inch nominal size, a 7 mm band width, and a 0.60 mm band thickness. Constructed from stainless steel, it resists corrosion in wet and chemically active environments. Installation requires a dedicated ear-clamp pincer tool that deforms the ear, locking the clamp in place without fasteners. This style of clamp is preferred where vibration resistance and a low-profile installation are required.\u003c\/p\u003e\u003cp\u003eThis ear clamp is suited for residential and light commercial work involving flexible hose, PEX tubing, corrugated gas connectors, and similar applications where a one-time, secure crimp connection is specified. Plumbers, HVAC technicians, and pipefitters commonly use ear clamps in hydronic heating systems, potable water systems, and refrigerant-line insulation jacketing. The 3.25-inch nominal size accommodates hoses and tubes at the upper range of standard residential piping diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.25-inch nominal clamp size for larger-diameter hose and tube connections\u003c\/li\u003e\n\u003cli\u003e7 mm band width distributes clamping force evenly around the hose\u003c\/li\u003e\n\u003cli\u003e0.60 mm band thickness provides a balance of flexibility during installation and strength after crimping\u003c\/li\u003e\n\u003cli\u003eStainless steel construction resists corrosion in wet, potable water, and hydronic environments\u003c\/li\u003e\n\u003cli\u003eSingle-ear design creates a permanent, tamper-resistant connection when closed with a pincer tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style single-ear clamp for use with flexible hose and tubing requiring a 3.25-inch nominal clamp diameter in plumbing, HVAC, and fluid-handling installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed with a calibrated ear-clamp pincer tool sized for this clamp style. Verify hose or tube outer diameter falls within the clamp's specified range before crimping. Once the ear is closed, the clamp cannot be reused. Follow applicable IPC or IFGC guidelines for connection standards in potable water or gas-line applications.\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: 3.25 inches\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: 0.60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Width of Ear\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\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: 16700081-100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OETIKER","offers":[{"title":"Default Title","offer_id":51540354171186,"sku":"16700081-100","price":16.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95e1a6b17d0ce4639801977fb020a27b.jpg?v=1785853121","url":"https:\/\/voomisupply.com\/products\/oetiker-16700081-100-ear-clamp-3-25-in-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
