Ipex 257196 Frpp Fusion Acid Waste 45 Elbow 4 Inches

Product Description

The IPEX 257196 is a 4-inch flame-retardant polypropylene (FRPP) 45-degree elbow designed for the Enfield electrofusion-joint drain, waste, and vent system. It handles corrosive chemical waste in non-return-air plenum environments and is built from FRPP with an operating temperature range of -10 degrees F to 212 degrees F, allowing systems to be flushed with boiling water. Heavy-gauge resistance wire is molded directly into the socket, eliminating loose components and ensuring controlled, repeatable fusion at each joint. Licensed plumbers and mechanical contractors install this fitting as part of a matched pipe-and-fitting system compliant with ASTM F1412 and listed to NSF 14 and IAPMO standards.

The IPEX 257196 is suited for laboratory, industrial, and commercial facilities that generate corrosive acid waste. Typical applications include chemical processing facilities, educational laboratories, healthcare facilities, and manufacturing plants where aggressive chemical drainage is required. The Enfield electrofusion system allows multiple joints to be prepared simultaneously, reducing total installation time and installed cost compared to borosilicate glass systems. A non-flame-retardant polypropylene (NFRPP) version is also available separately upon request.

Key Features

• Flame-retardant polypropylene (FRPP) construction rated for corrosive chemical waste drainage
• Electrofusion joints complete in approximately 2 minutes, supporting faster rough-in schedules
• Operating temperature range of -10 degrees F to 212 degrees F, compatible with boiling-water flush procedures
• Heavy-gauge resistance wire molded into sockets eliminates loose components and ensures joint repeatability
• Matched pipe-and-fitting system simplifies installation and supports long-term reliability
• Compliant with ASTM F1412 and ASTM D4101; listed to NSF 14 and IAPMO

Compatibility

Designed for use within the IPEX Enfield electrofusion acid waste system. Pipe and fittings in the Enfield line are matched components intended to work together; use of non-Enfield pipe or fittings with this fitting is not specified by the manufacturer. Compatible with virtually all non-return-air plenum chemical waste drainage applications.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor familiar with electrofusion joining procedures and applicable plumbing codes, including IPC and IAPMO guidelines. Shut off all flow and depressurize the drain system before cutting into an existing line. Use the manufacturer-specified Enfusion microprocessor-controlled fusion unit to ensure proper joint formation; do not substitute generic heat sources. Confirm that the pipe ends and socket interiors are clean and dry before initiating the fusion cycle.
