Constructed from 18-gauge carbon steel with a galvanized plated finish, it fits a 4-inch pipe size with a 4.5-inch inner diameter and a 10-inch shield length. It is used by plumbers and mechanical contractors wherever insulated piping passes through hanger supports, preventing insulation compression and damage at the bearing point.\u003c\/p\u003e\n\u003cp\u003eThis shield is suited for residential and commercial mechanical systems where foam, fiberglass, or high-density insulation must be preserved at hanger locations. The galvanized finish provides corrosion resistance in typical indoor mechanical room and plenum environments. Each order ships in a packaging quantity of 25 shields, making it practical for new construction and retrofit piping runs with multiple hanger points.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-gauge carbon steel construction for rigid support at hanger contact points\u003c\/li\u003e\n  \u003cli\u003eGalvanized plated finish resists corrosion in mechanical environments\u003c\/li\u003e\n  \u003cli\u003e4.5-inch inner diameter fits over insulation on 4-inch pipe\u003c\/li\u003e\n  \u003cli\u003e10-inch shield length distributes load across the hanger bearing area\u003c\/li\u003e\n  \u003cli\u003eCompatible with foam, fiberglass, and high-density pipe insulation types\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 25 for multi-hanger installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style insulation shield for use with standard pipe hangers on 4-inch pipe carrying foam, fiberglass, or high-density insulation in commercial and residential mechanical piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers or mechanical contractors following IPC and IFGC hanger spacing requirements. The shield is placed around the insulation before the hanger is tightened so the hanger bears on the steel shield rather than directly on the insulation. Inspect shield seating and ensure the insulation is not compressed beyond the shield edges before final tightening. No cutting or field modification of the shield is required for standard installations on 4-inch pipe.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShield Inner Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShield Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShield Thickness\u003c\/strong\u003e: 18 gauge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShield Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Galvanized Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insulation Types\u003c\/strong\u003e: Foam, Fiberglass, High-Density Insulation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaging Quantity\u003c\/strong\u003e: 25\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: WARWICK HANGER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1551-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WARWICK HANGER","offers":[{"title":"Default Title","offer_id":51268968841522,"sku":"1551-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913635.jpg?v=1780711324","url":"https:\/\/voomisupply.com\/products\/warwick-hanger-1551-4-pipe-insulation-shield-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
