Part of the IPEX Enfield electrofusion-joint system, this coupling forms a secure, leak-resistant joint using a heavy-gauge resistance wire molded directly into the socket. A microprocessor-controlled fusion unit drives the joint process, producing reliable, repeatable connections in approximately 2 minutes. The Enfield system is manufactured from FRPP with an operating temperature range of -10 degrees F to 212 degrees F, allowing system flushing with boiling water. Licensed plumbers and mechanical contractors install this fitting in laboratory, industrial, and institutional drain systems handling corrosive waste.\u003c\/p\u003e\n\u003cp\u003eThe 257153 is suited for non-return-air-plenum chemical waste drain, waste, and vent applications in residential laboratory settings, commercial facilities, and industrial plants where acid waste drainage is required. The FRPP construction resists a broad range of corrosive chemicals, making it appropriate for laboratory drain systems, semiconductor fabs, pharmaceutical facilities, and similar environments. A non-flame-retardant polypropylene (NFRPP) version is also available separately for applications where flame-retardant classification is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eElectrofusion joint technology produces secure, repeatable connections in approximately 2 minutes, reducing installation time versus traditional joining methods\u003c\/li\u003e\n  \u003cli\u003eHeavy-gauge resistance wire molded into sockets eliminates loose components and ensures controlled, consistent fusion\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -10 degrees F to 212 degrees F supports boiling-water system flushing\u003c\/li\u003e\n  \u003cli\u003eEasy-connect heavy-duty socket terminal posts with protection ears simplify connections even in confined spaces\u003c\/li\u003e\n  \u003cli\u003eMaintenance-free joints with no breakage risk, offering an installed cost advantage over glass pipe systems\u003c\/li\u003e\n  \u003cli\u003eMultiple joints can be fused simultaneously, supporting faster project completion on large systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use within the IPEX Enfield electrofusion-joint system. Compatible pipe and fittings comply with ASTM F1412 for polyolefin pipe and fittings for corrosive waste drainage systems and ASTM D4101 for polypropylene injection and extrusion materials. Listed to NSF 14 and IAPMO standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed plumber or pipefitter familiar with electrofusion joining procedures and the Enfield Enfusion control unit. De-energize and isolate the waste system before making any connections to existing piping. Follow IPC and local plumbing code requirements for acid waste drainage systems, including proper venting and material approvals. Do not attempt to join Enfield FRPP fittings using solvent cement or mechanical methods — the electrofusion process is the only approved joining method for this system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Flame-Retardant Polypropylene (FRPP)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJoining Method\u003c\/strong\u003e: Electrofusion\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: -10 degrees F to 212 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard Compliance\u003c\/strong\u003e: ASTM F1412, ASTM D4101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListings\u003c\/strong\u003e: NSF 14, IAPMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Corrosive chemical acid waste drainage\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: IPEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 257153\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IPEX","offers":[{"title":"Default Title","offer_id":51468244189490,"sku":"257153","price":75.88,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/ipex-257153-frpp-fusion-acid-waste-coupling-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
