Manufactured from stainless steel, this clamp delivers corrosion resistance suited to wet or chemically active environments. The nominal size is 2-5\/16 inches, with a band width of 7 millimeters and a band thickness of 0.6 millimeters. The inner ear width measures 10 millimeters, providing consistent pinching geometry when closed with standard ear-clamp pliers or a pincering tool. Licensed trades and experienced technicians use single-ear clamps where a vibration-resistant, tamper-evident closure is required over barbed or stepped fittings.\u003c\/p\u003e\u003cp\u003eThis clamp is suited for residential and light commercial installations where hoses, tubing, or flexible connectors must be secured without the risk of loosening over time. Common applications include refrigerant-line insulation sleeves, radiant heating tubing connections, PEX fittings, and coolant hose assemblies. The ear-style design is a preferred choice when low-profile clearance around the fitting is a priority and when the joint must remain stable under continuous pressure cycling or vibration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNominal clamp size of 2-5\/16 inches for compatibility with standard hose and tube ODs in that range\u003c\/li\u003e\n\u003cli\u003eStainless steel construction provides corrosion resistance in wet, outdoor, and chemically active environments\u003c\/li\u003e\n\u003cli\u003e7 millimeter band width distributes clamping load evenly across the hose surface\u003c\/li\u003e\n\u003cli\u003e0.6 millimeter band thickness balances rigidity with consistent ear-closure deformation\u003c\/li\u003e\n\u003cli\u003e10 millimeter inner ear width designed for use with standard ear-clamp pincer tooling\u003c\/li\u003e\n\u003cli\u003eSingle-ear design creates a permanent, vibration-resistant closure once pinched\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style ear clamp for hose and tubing connections requiring a nominal diameter of 2-5\/16 inches across plumbing, HVAC, and fluid-system applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a calibrated ear-clamp pincer or pincering pliers rated for the clamp size. Depressurize and drain the system before removing or replacing any hose clamp. Position the clamp over the hose and onto the barb or fitting shoulder before closing the ear. Once the ear is pinched, the clamp is permanent and cannot be reopened without cutting.\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: 2-5\/16 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 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBand Thickness\u003c\/strong\u003e: 0.6 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Ear Width\u003c\/strong\u003e: 10 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31162901\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: 16704689-100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OETIKER","offers":[{"title":"Default Title","offer_id":51539618758962,"sku":"16704689-100","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/654335b7f80fda7a2c28d218de5ba6e2.jpg?v=1785843544","url":"https:\/\/voomisupply.com\/products\/oetiker-16704689-100-ear-clamp-2-5-16-in-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
