This fitting handles corrosive chemical waste streams in laboratory, industrial, and institutional drain systems where standard PVC or ABS fittings are not suitable. The FRPP material carries an operating temperature range of -10 degrees F to 212 degrees F, allowing systems to be flushed with boiling water without joint failure. Heavy-gauge resistance wire is molded directly into the socket, eliminating loose components and ensuring controlled, repeatable fusion. Joints are completed in approximately 2 minutes using the Enfusion microprocessor-controlled unit. Licensed plumbers and pipefitters install this fitting where corrosive waste drainage code compliance is required.\u003c\/p\u003e\n\u003cp\u003eThe 257174 is part of the Enfield FRPP product line, designed for non-return-air plenum chemical waste drain applications in research labs, semiconductor facilities, pharmaceutical plants, and similar environments. The electrofusion joint system produces secure, maintenance-free connections rated for long-term chemical resistance. A non-flame-retardant polypropylene (NFRPP) version is also available separately for installations where FRPP is not required. The sweep geometry of this 90-degree elbow reduces flow restriction and aids drainage of viscous or particulate-laden waste streams.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFlame-retardant polypropylene (FRPP) construction rated for corrosive chemical waste drainage\u003c\/li\u003e\n  \u003cli\u003eElectrofusion socket with molded heavy-gauge resistance wire — no loose components\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -10 degrees F to 212 degrees F, compatible with boiling-water flush\u003c\/li\u003e\n  \u003cli\u003eFusion joints completed in approximately 2 minutes, allowing multiple simultaneous joints\u003c\/li\u003e\n  \u003cli\u003eMicroprocessor-controlled Enfusion unit ensures joint repeatability and security\u003c\/li\u003e\n  \u003cli\u003eComplies with ASTM F1412, ASTM D4101, NSF 14, and IAPMO listing requirements\u003c\/li\u003e\n  \u003cli\u003eSweep 90-degree geometry reduces flow restriction in acid waste drain lines\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.

De-energize and isolate the drain system and allow it to cool before cutting into an existing line. Use the Enfusion control unit according to the manufacturer's fusion cycle procedure — do not substitute with generic heat sources. Allow completed joints to cool undisturbed for the manufacturer-specified cure period before pressurizing or flowing waste through the line.\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\u003eFitting Type\u003c\/strong\u003e: Sweep 90 Elbow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJoint Type\u003c\/strong\u003e: Electrofusion (Enfield System)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Flame-Retardant Polypropylene (FRPP)\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: 257174\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IPEX","offers":[{"title":"Default Title","offer_id":51468556075314,"sku":"257174","price":140.69,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/ipex-257174-frpp-acid-waste-sweep-90-elbow-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
