Fuseal Combo Wye & Bend 90° S x S x S

  Datasheet (PDF)

The Georg Fischer Fuseal Combo Wye & 1/8 Bend 90° 6" S x S x S is an engineered flame-retardant polypropylene drainage fitting designed for corrosive chemical DWV networks. Fabricated to integrate a 45-degree wye with an eighth bend into a smooth 90-degree sweep, this 6-inch socket-ended fitting directs laboratory and industrial waste flows efficiently while maintaining high resistance to corrosive chemicals, salts, and thermal spikes.

Technical specifications

The Fuseal 6-inch combo wye and eighth bend fitting features an integrated sweep geometry with three socket hubs engineered for electrofusion joining. Its flame-retardant polypropylene formulation provides lasting structural integrity and chemical inertness across rigorous industrial drainage environments.

• Nominal size: 6 inches (Socket x Socket x Socket)
• Material: Flame-retardant polypropylene (PPFR)
• Thermal performance: Continuous duty up to 180 degrees F (82 degrees C); intermittent discharges up to 212 degrees F (100 degrees C)
• Chemical resistance: Inert to alkalis, alcohols, dilute mineral acids, solvents, and salt solutions
• Operational restrictions: Attacked by strong oxidizing acids; degraded by certain organic solvents and chlorinated hydrocarbons
• Joint configuration: Electrofusion socket connection (Part No. 527306F)

Applications

This combined wye fitting is designed for gravity and low-head chemical drainage, waste, and vent (DWV) piping systems. It serves as an inert alternative to metal systems prone to electrolytic rust, pitting, and rapid acid corrosion.

Primary installations include life science research centers, pharmaceutical facilities, hospital utility networks, university chemistry laboratories, and industrial chemical processing plants. The gradual sweep profile ensures laminar flow transitions when merging major branch waste streams into main horizontal runs.

Installation and jointing

Joint assembly relies on the Fuseal electrofusion socket process to produce high-strength, leak-free fused interfaces. Electrical resistance heating creates an integrated melt zone between the fitting socket and the mating polypropylene pipe.

For 6-inch joints, installation requires Fuseal fusion locking collars without plastic clamps, supported by metal clamping tools and the automated Electro Plus fusion machine. Installers must cut pipes square, remove all burrs, apply the recommended chamfer, and thoroughly abrade the joint surfaces prior to initiating the fusion cycle.
