The dual-grommet construction cushions the pipe against vibration and prevents direct metal-to-metal contact between the pipe and structural framing. It is used wherever a pipe must pass through or hang from a wall, floor joist, or framing member in residential and light commercial plumbing installations. Licensed plumbers and mechanical contractors install this fitting as part of a code-compliant pipe support strategy.\u003c\/p\u003e\n\u003cp\u003eThis insulator is suited for water supply lines, hydronic distribution piping, and other CTS pipe applications where noise isolation and movement control are required. It accommodates both 1\/2 inch and 3\/4 inch CTS pipe, making it a versatile single-stock item for service vans and supply rooms. The twin grommet design is particularly useful in copper pipe installations where thermal expansion and pipe movement must be absorbed without abrasion or stress concentrations at the support point.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwin grommet construction isolates pipe from framing to reduce vibration transmission and noise\u003c\/li\u003e\n  \u003cli\u003eFits both 1\/2 inch and 3\/4 inch CTS pipe, covering two common supply line sizes in one part\u003c\/li\u003e\n  \u003cli\u003eReplaces legacy parts 558-M2 and 558-M3, consolidating two SKUs into one\u003c\/li\u003e\n  \u003cli\u003eDesigned for through-framing and hanging support applications in plumbing rough-in work\u003c\/li\u003e\n  \u003cli\u003ePrevents direct contact between copper pipe and structural members, reducing corrosion risk at contact points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct replacement for SIOUX CHIEF 558-M2 and 558-M3 insulators.

Shut off the water supply and depressurize the line before repositioning any existing pipe supports. Verify that the insulator grommet fully seats around the pipe and that the eye bracket is fastened securely to the framing member per local IPC requirements. Do not over-compress the grommet during fastening, as this can reduce its vibration-damping effectiveness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size Range\u003c\/strong\u003e: 1\/2 inch to 3\/4 inch CTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrommet Type\u003c\/strong\u003e: Twin grommet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 739236201607\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIOUX CHIEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 558-M23\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIOUX CHIEF","offers":[{"title":"Default Title","offer_id":51383542513970,"sku":"558-M23","price":32.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672736.png?v=1782599963","url":"https:\/\/voomisupply.com\/products\/sioux-chief-558-m23-cts-pipe-eye-insulator-twin-grommet","provider":"Voomi Supply","version":"1.0","type":"link"}
