Ipex 257394 Frpp Electrofusion Acid Waste Wye 3 Inches

Product Description

The IPEX 257394 is a 3-inch flame-retardant polypropylene (FRPP) acid waste wye fitting designed for use in the Enfield electrofusion-joint drainage system. It handles corrosive chemical waste in non-return-air plenum applications where standard PVC or cast iron fittings are not suitable. The fitting is manufactured from FRPP with an operating temperature range of -10 degrees F to 212 degrees F, allowing systems to be flushed with boiling water without damaging the joint. Heavy-gauge resistance wire is molded directly into each socket, enabling a microprocessor-controlled fusion process that produces a secure, repeatable joint in approximately 2 minutes. Licensed plumbers and mechanical contractors install this fitting as part of a matched pipe-and-fitting system.

The 257394 is intended for corrosive chemical waste drainage systems in laboratory, industrial, and institutional settings where acid-resistant materials are required. The Enfield FRPP system is suited for non-return-air plenum environments and is a direct alternative to borosilicate glass waste systems. Its electrofusion joining method allows multiple joints to be set simultaneously, reducing overall installation time on larger projects. The matched pipe and fitting system is designed to provide long-term reliability with minimal maintenance in demanding chemical environments.

Key Features

• Flame-retardant polypropylene (FRPP) construction rated for corrosive chemical waste service
• Operating temperature range of -10 degrees F to 212 degrees F, compatible with boiling water flush cycles
• Heavy-gauge resistance wire molded into sockets eliminates loose components and ensures controlled, repeatable fusion
• Electrofusion joints complete in approximately 2 minutes, allowing multiple joints to be made simultaneously
• Listed to NSF 14 and IAPMO; complies with ASTM F1412 and ASTM D4101
• Maintenance-free design with no breakage risk compared to glass waste systems

Compatibility

The 257394 is part of the IPEX Enfield electrofusion-joint system and is designed to work with Enfield FRPP pipe and fittings for corrosive waste drainage applications. The system complies with ASTM F1412 for polyolefin pipe and fittings for corrosive waste drainage systems.

Installation Notes

Installation is performed by licensed plumbers or mechanical contractors familiar with electrofusion joining procedures. Power down and isolate the waste system before making any connections. Use only the Enfield Enfusion microprocessor-controlled fusion unit to ensure proper joint formation — do not attempt heat-gun or solvent-cement joining on electrofusion fittings. Follow applicable plumbing codes, including IPC and local authority requirements, for chemical waste drainage system installations.
