Ipex 257033 Frpp Fusion Acid Waste 90 Elbow 6 Inches

Product Description

The IPEX 257033 is a 6-inch flame-retardant polypropylene (FRPP) 90-degree elbow engineered for the Enfield electrofusion-joint drain system. It is designed to handle corrosive chemical waste in demanding non-return-air plenum environments. The fitting is manufactured from FRPP material rated for continuous service from -10 degrees F to 212 degrees F, allowing systems to be flushed with boiling water without degradation. Heavy-gauge resistance wire is molded directly into the socket, eliminating loose components and delivering controlled, repeatable fusion joints in approximately two minutes. Licensed plumbers and corrosive-waste system installers are the primary trade for this fitting.

This elbow is used in laboratory, industrial, and institutional drain systems where chemical resistance and flame-retardancy are code requirements. It is suited for horizontal and vertical direction changes in acid-waste drainage piping routed through non-plenum spaces. The Enfield system is designed so that multiple joints can be fused simultaneously, reducing labor time on larger installations. A non-flame-retardant polypropylene (NFRPP) version is available separately for applications where FRPP is not required.

Key Features

• Electrofusion joint technology produces reliable connections in approximately 2 minutes, reducing overall installation time
• Heavy-gauge resistance wire molded into sockets eliminates loose components and ensures controlled fusion
• FRPP material rated from -10 degrees F to 212 degrees F supports boiling-water flushing of drain systems
• Heavy-duty socket terminal posts with protection ears simplify connections even in confined or difficult access areas
• Microprocessor-controlled Enfusion unit ensures joint repeatability across all fittings in the system
• Maintenance-free joints with no breakage factor, comparable installed cost significantly lower than borosilicate glass systems

Compatibility

Designed for use within the IPEX Enfield electrofusion acid-waste drain system. Pipe and fittings comply with ASTM F1412 for polyolefin pipe and fittings for corrosive waste drainage systems, and the base material complies with ASTM D4101 for polypropylene injection and extrusion materials. All fittings are listed to NSF 14 and IAPMO.

Installation Notes

Installation must be performed by a licensed plumber or qualified corrosive-waste piping installer familiar with electrofusion jointing procedures and applicable plumbing codes including the IPC and IFGC where referenced locally. De-energize and isolate the existing drain system before cutting into any active line. Use the Enfusion microprocessor-controlled fusion unit matched to this system — do not attempt fusion with generic heat tools. Verify terminal post connections are secure and protection ears are undamaged before initiating the fusion cycle.
