Ipex 257391 Frpp Fusion Acid Waste Reducing Wye 2x1.5 in

Product Description

The IPEX 257391 is a flame-retardant polypropylene (FRPP) electrofusion reducing wye fitting designed for corrosive chemical waste drainage systems. Part of the Enfield electrofusion-joint system, this fitting uses a microprocessor-controlled fusion process to form secure, leak-resistant joints in approximately 2 minutes. It transitions from a 2-inch inlet to a 1-1/2-inch outlet and is suitable for systems handling aggressive acids and chemical waste. Licensed plumbers and mechanical contractors install this fitting in laboratories, manufacturing facilities, and institutional buildings where chemical drainage requires non-metallic, corrosion-resistant piping. The FRPP material supports an operating temperature range from -10 degrees F to 212 degrees F, allowing systems to be flushed with boiling water.

The 257391 reducing wye is used in non-return-air-plenum chemical waste drain, waste, and vent (DWV) piping systems. Its flame-retardant rating makes it appropriate for installations where building codes require fire-rated materials in the pipe run. Typical applications include laboratory drain systems, semiconductor fabrication facilities, pharmaceutical plants, and other commercial or industrial environments where conventional PVC or cast iron is incompatible with the chemical load. The Enfield system is a matched pipe-and-fitting platform, meaning pipe and fittings are engineered together for dimensional consistency and long-term joint reliability.

Key Features

• Electrofusion joints form in approximately 2 minutes, reducing labor time compared to solvent-weld or mechanical systems
• Heavy-gauge resistance wire molded directly into sockets eliminates loose components and ensures controlled, repeatable fusion
• Heavy-duty socket terminal posts with protective ears provide easy, reliable connections even in confined spaces
• Operating temperature range of -10 degrees F to 212 degrees F supports hot-water flushing and elevated-temperature waste streams
• Flame-retardant polypropylene (FRPP) construction meets requirements for non-return-air-plenum chemical waste applications
• Maintenance-free once installed; no breakage concerns associated with borosilicate glass systems

Compatibility

Designed for use within the IPEX Enfield electrofusion-joint system as an OEM-matched fitting for FRPP corrosive waste drainage piping. Pipe and fittings comply with ASTM F1412 and material requirements of ASTM D4101. All fittings are listed to NSF 14 and certified by IAPMO.

Installation Notes

Installation of electrofusion polypropylene chemical waste fittings should be performed by a licensed plumber familiar with IAPMO-listed systems and applicable local plumbing codes. Before making any fusion joints, shut off flow to the drain system and ensure the pipe ends and fitting sockets are clean, dry, and properly prepared per the Enfield system instructions. Use the microprocessor-controlled Enfusion unit specified for this system to guarantee joint integrity and repeatability. Do not use open-flame heat sources or standard solvent cements with FRPP electrofusion fittings.
