The seal body is constructed from EPDM rubber and is rated for temperatures up to 175 degrees F. The S series ships with S316 stainless steel nuts and bolts, which have been salt spray tested to 1,470 hours, making it suitable for corrosive or wet environments. Pressure resistance is rated to 20 psig, equivalent to 40 feet of head. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers for this type of fitting.\u003c\/p\u003e\u003cp\u003eThe ls-475-s is used in residential and commercial construction wherever a pipe penetrates a structural element such as a concrete wall, floor slab, or ceiling assembly. It accommodates pipes of varying diameters by linking individual rubber links around the pipe and drawing them tight with the included hardware. Typical applications include utility entries, mechanical room penetrations, and below-grade wall passages where moisture ingress or hydrostatic pressure must be controlled.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePressure resistant to 20 psig (40 feet of head) for positive hydrostatic sealing\u003c\/li\u003e\n\u003cli\u003eEPDM rubber body rated to 175 degrees F for broad temperature compatibility\u003c\/li\u003e\n\u003cli\u003eS316 stainless steel hardware, salt spray tested to 1,470 hours for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eModular link design accommodates pipes of varying sizes without special tools\u003c\/li\u003e\n\u003cli\u003eISO approved construction for quality assurance in commercial and industrial projects\u003c\/li\u003e\n\u003cli\u003eCompatible with walls, floors, and ceilings in a single seal design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with pipes of any size passing through walls, floors, and ceilings in residential and commercial construction. The modular link format adapts to various pipe outside diameters. Specific pipe size compatibility should be confirmed against the LINK-SEAL sizing chart using the pipe outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or mechanical contractors following applicable plumbing and mechanical codes. Before installing, verify the annular space dimensions and pipe outside diameter against the seal size rating. No special tools are required beyond standard hand tools to tighten the stainless steel hardware. Do not overtighten the links, as excessive torque can deform the rubber elements and reduce sealing effectiveness.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Body Material\u003c\/strong\u003e: EPDM rubber (black)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware Material\u003c\/strong\u003e: S316 stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardware Corrosion Rating\u003c\/strong\u003e: 1,470 hour salt spray tested\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 175 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 20 psig (40 feet of head)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S (stainless steel hardware)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LINK-SEAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ls-475-s\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LINK-SEAL","offers":[{"title":"Default Title","offer_id":51149504741682,"sku":"LS-475-S","price":44.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305987398.jpg?v=1778595698","url":"https:\/\/voomisupply.com\/products\/link-seal-ls-475-s-modular-pipe-penetration-seal","provider":"Voomi Supply","version":"1.0","type":"link"}
