Manufactured by Chemtrol under Model 4501-R, this fitting uses a slip and socket weld connection method for a solvent-cemented joint. The body is molded from Type 1, Grade I PVC cell class 12454 material conforming to ASTM D1784 and ASTM D2467, giving it the wall thickness and pressure rating expected of SCH 80 fittings. It is rated to 140 degrees F and carries NSF\/ANSI Standard 14 and 61 Annex G certification, making it suitable for potable water and chemical handling applications.\u003c\/p\u003e\u003cp\u003eThis reducing coupling is used in residential and commercial plumbing, industrial process piping, and pool and spa circulation systems where a Schedule 80 gray PVC fitting is specified. The slip socket end accepts standard IPS pipe for solvent cement installation. It is a common choice for mechanical rooms, pump stations, and chemical feed lines where a step-down in pipe diameter is needed mid-run or at equipment connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSchedule 80 wall thickness for higher pressure ratings compared to SCH 40 fittings\u003c\/li\u003e\n\u003cli\u003eSlip and socket weld connection for standard solvent cement installation\u003c\/li\u003e\n\u003cli\u003ePVC Type 1 Grade I material per ASTM D1784 and ASTM D2467\u003c\/li\u003e\n\u003cli\u003eRated to 140 degrees F continuous service temperature\u003c\/li\u003e\n\u003cli\u003eNSF\/ANSI 14 and 61 Annex G listed for potable water service\u003c\/li\u003e\n\u003cli\u003eGray molded finish consistent with Schedule 80 PVC system components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for Schedule 80 PVC piping systems using 3-inch to 1.5-inch reducing connections with solvent cement slip socket ends.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC and local plumbing code requirements. Shut off and depressurize the piping system completely before cutting into the line. Use only PVC Schedule 80-rated solvent cement and primer rated for the service conditions; do not substitute SCH 40 cement. Allow full cure time per the cement manufacturer instructions before returning the system to pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3 inches x 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Slip and Socket Weld\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSchedule\u003c\/strong\u003e: Schedule 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC Type 1 Grade I Cell Class 12454\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Standard\u003c\/strong\u003e: ASTM D1784, ASTM D2467\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 140 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMethod of Manufacture\u003c\/strong\u003e: Molded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standards\u003c\/strong\u003e: NSF\/ANSI Standard 14 and 61 Annex G\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MACOMB GROUP APPROVED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 829-337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MACOMB GROUP","offers":[{"title":"Default Title","offer_id":68103253721394,"sku":"829-337","price":60.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/293844594.jpg?v=1793301123","url":"https:\/\/voomisupply.com\/products\/macomb-group-approved-829-337-pvc-sch-80-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
