Formed from stainless steel, it provides corrosion resistance in wet or chemically active environments. The ear design allows the clamp to be closed with standard ear clamp pliers or a pincer tool, creating a uniform 360-degree compression around the hose. With a 7 mm band width and 0.6 mm wall thickness, this clamp is sized for 1-3\/8 inch nominal diameter connections and delivers a consistent, vibration-resistant seal that meets the demands of professional installation work.\u003c\/p\u003e\u003cp\u003eThis ear clamp is suited for residential and light commercial use across HVAC, plumbing, and pool or fluid-distribution systems. It is commonly used to secure flexible hoses, PEX transitions, radiator hoses, and similar tubing where a permanent, tamper-evident connection is required. Licensed plumbers, HVAC technicians, and pool service professionals select single-ear clamps when a low-profile, factory-quality crimp is preferred over a worm-drive alternative. The compact form factor makes it practical in tight or confined spaces where a screw-type clamp would be difficult to torque properly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-ear stepless design creates permanent, uniform 360-degree hose compression\u003c\/li\u003e\n\u003cli\u003eStainless steel construction resists corrosion in wet and chemical environments\u003c\/li\u003e\n\u003cli\u003e1-3\/8 inch nominal size fits standard hose and tubing at that diameter\u003c\/li\u003e\n\u003cli\u003e7 mm band width distributes clamping force evenly across the hose surface\u003c\/li\u003e\n\u003cli\u003e0.6 mm band thickness provides strength while keeping a low-profile fit\u003c\/li\u003e\n\u003cli\u003eLow-profile ear closure is compatible with standard ear clamp pincer tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install ear clamp for 1-3\/8 inch nominal diameter flexible hoses and tubing in plumbing, HVAC, and fluid-handling systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a dedicated ear clamp closing tool or pincer pliers rated for the clamp band width. Shut off water supply or system pressure and relieve line pressure completely before servicing any hose connection. Once closed, the ear deforms permanently and the clamp cannot be reopened or reused. Follow applicable plumbing or mechanical codes, including IPC and IFGC guidelines, for hose connection and fitting 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: 1-3\/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\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: 16704169-100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OETIKER","offers":[{"title":"Default Title","offer_id":51541232091442,"sku":"16704169-100","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2f88f045fc366b95cd9ad1cc58fca6c.jpg?v=1785870406","url":"https:\/\/voomisupply.com\/products\/oetiker-16704169-100-ear-clamp-1-3-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
