This coupling accommodates nominal sizes of 1-1\/2 or 1-1\/4 inches on one end and 1-1\/4 or 1 inch on the other, making it a practical solution for transitioning between standard pipe sizes without additional fittings. It is compatible with copper, plastic, and steel pipe end styles and is rated for Schedule 40 and standard-wall pipe. Licensed plumbers and pipe fitters install this fitting during new construction, renovation, or repair work where dissimilar or stepped pipe connections are required.\u003c\/p\u003e\n\u003cp\u003eThis specialty coupling is suited for residential and light commercial plumbing applications, particularly in drain, waste, and vent configurations where transitions between copper, plastic, and steel pipe materials or sizes occur within the same run. The shielded design provides a secure mechanical connection that maintains alignment and resists separation. It is manufactured domestically and follows SCH 40 and standard-wall dimensional standards, ensuring a reliable fit with commonly available pipe stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eShielded K Series design provides a secure, aligned mechanical joint at the coupling\u003c\/li\u003e\n  \u003cli\u003eAccepts nominal sizes 1-1\/2 or 1-1\/4 inches on one end and 1-1\/4 or 1 inch on the other end\u003c\/li\u003e\n  \u003cli\u003eCompatible with copper, plastic, and steel pipe end styles\u003c\/li\u003e\n  \u003cli\u003eRated for Schedule 40 and standard-wall pipe\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style specialty transition coupling for Schedule 40 and standard-wall copper, plastic, and steel pipe in residential and commercial drain, waste, and vent plumbing systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis coupling is installed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before beginning work. Ensure pipe ends are cut cleanly, deburred, and free of debris before seating them into the coupling. Tighten the coupling bands evenly and in sequence using the appropriate hand tools to achieve a proper seal without over-torquing the clamp hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: K Series Shielded Specialty Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size (End 1)\u003c\/strong\u003e: 1-1\/2 or 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size (End 2)\u003c\/strong\u003e: 1-1\/4 or 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible End Styles\u003c\/strong\u003e: Copper, Plastic, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Schedule Rating\u003c\/strong\u003e: SCH 40 \/ Standard Wall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Domestic\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: MISSION RUBBER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 801613\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MISSION RUBBER","offers":[{"title":"Default Title","offer_id":51524949672242,"sku":"K1125","price":52.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/62366620c5a9d1bb09a0f54542b37da6_c0568a01-4d80-4e4d-b328-6cf866c6ec14.jpg?v=1785462146","url":"https:\/\/voomisupply.com\/products\/mission-rubber-801613-k-series-shielded-coupling-sch-40","provider":"Voomi Supply","version":"1.0","type":"link"}
