Molded from UV-stabilized, weather-resistant, fire-resistant PVC, this coupling is rated for exterior exposure from -4 degrees F to 140 degrees F. It protects refrigerant tubing, condensate hose, and low-voltage control wiring from weather, debris, and pests. HVAC technicians install it during mini split and heat pump line set routing where duct runs must be extended without breaking the protective channel.\u003c\/p\u003e\n\u003cp\u003eThis coupling is intended for residential and light commercial mini split and heat pump installations where SlimDuct SD100 series duct channel is used to enclose line sets along exterior walls or interior runs. The white finish is matched to SlimDuct white duct channels for a uniform appearance. It is used wherever a clean, in-line extension of the duct run is required between two SD100 duct sections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 3.75-inch SlimDuct SD100 series duct channel sections\u003c\/li\u003e\n  \u003cli\u003eUV-stabilized PVC construction rated for exterior exposure\u003c\/li\u003e\n  \u003cli\u003eTemperature range: -4 degrees F to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003eSnap-together engagement for secure, aligned connection\u003c\/li\u003e\n  \u003cli\u003eProtects refrigerant tubing, condensate lines, and control wiring\u003c\/li\u003e\n  \u003cli\u003eWhite finish matches SlimDuct white duct channel for cohesive appearance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with RECTORSEAL SlimDuct SD100 series 3.75-inch duct channel sections in mini split and heat pump line set enclosure applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLicensed HVAC technicians typically install this coupling as part of a complete line set enclosure during mini split or heat pump commissioning or service. Power down the mini split system before routing or modifying any line set enclosure. Verify that refrigerant tubing, condensate hose, and control wiring are properly positioned inside the duct channel before engaging the coupling. Secure duct channel runs to the mounting surface per local mechanical code requirements before snapping the coupling into place.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Width\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: UV-stabilized, weather-resistant, fire-resistant PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -4 degrees F to 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SD100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Snap-together inline coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Exterior and interior line set enclosure\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: RECTORSEAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SD-SJ100W\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51346622316850,"sku":"SD-SJ100W","price":28.42,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555135.jpg?v=1782085715","url":"https:\/\/voomisupply.com\/products\/rectorseal-sd-sj100w-slimduct-straight-coupling-3-75-in-white","provider":"Voomi Supply","version":"1.0","type":"link"}
