The clamp features a 1-1\/4 inch closed diameter, a 7 mm band width, and a 0.75 mm band thickness, all in carbon steel construction. Once crimped with the appropriate pincer tool, the ear deforms to lock the clamp at a fixed diameter, eliminating the loosening risk associated with screw-type clamps. HVAC technicians, plumbers, and refrigeration mechanics install this style of clamp where a low-profile, permanent seal is required.\u003c\/p\u003e\u003cp\u003eThis clamp is suited for residential and light commercial applications involving flexible hose or tubing connections. Typical uses include condensate drain lines, coolant hoses, PEX-to-barb fittings, and similar tubing assemblies where a compact, non-adjustable clamp is preferred over a worm-gear or T-bolt style. The single-ear design keeps the installed profile small, which is useful in tight equipment cabinets or confined chases.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-ear stepless design provides a permanent, tamper-evident crimp connection\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch closed diameter fits standard hose and tubing of that size\u003c\/li\u003e\n\u003cli\u003e7 mm band width distributes clamping force evenly across the hose surface\u003c\/li\u003e\n\u003cli\u003e0.75 mm band thickness provides consistent crimping without distorting the hose barb\u003c\/li\u003e\n\u003cli\u003eCarbon steel construction delivers reliable strength for common indoor fluid-handling service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation clamp for 1-1\/4 inch hose and tubing connections in HVAC, plumbing, and fluid-handling assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a dedicated single-ear clamp pincer tool or crimping tool sized for this clamp style. Shut off fluid flow and relieve any system pressure before removing an existing clamp or fitting. Seat the hose fully onto the barb fitting before positioning the clamp over the ear, and verify the ear is centered over the barb before crimping. Carbon steel clamps are intended for dry or indoor-protected environments; inspect for corrosion if used in high-moisture areas over time.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamp Type\u003c\/strong\u003e: 1-Ear Stepless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClosed Diameter\u003c\/strong\u003e: 1-1\/4 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: 0.75 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon Steel\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: 10500343\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OETIKER","offers":[{"title":"Default Title","offer_id":51523563192626,"sku":"10500343","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37f2d2805eb3840fc4bfc9ed65c9ab5c.webp?v=1785442786","url":"https:\/\/voomisupply.com\/products\/oetiker-10500343-1-ear-clamp-1-1-4-inches-carbon-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
