P-Trap PP 8-12 inch S x S

  Datasheet (PDF)

The Georg Fischer Fuseal large-diameter polypropylene P-trap provides a reliable liquid barrier against noxious sewer gases in corrosive drainage, waste, and vent piping networks. Designed with socket-by-socket (S x S) connections for 8-inch to 12-inch lines, this fitting is available in both flame-retardant (PPFR) and non-flame-retardant (PPNFR) formulations. It handles continuous operating temperatures up to 180 degrees Fahrenheit (82 degrees Celsius) and intermittent discharge temperatures up to 212 degrees Fahrenheit (100 degrees Celsius).

Technical specifications

The Georg Fischer Fuseal P-trap maintains an integral water seal to prevent hazardous vapor backflow while ensuring unobstructed chemical waste conveyance. Its engineered thermoplastic body offers robust structural integrity suitable for industrial gravity and low-pressure drainage systems.

• Material options: Flame retardant polypropylene (PPFR) and non-flame retardant polypropylene (PPNFR)
• Connection profile: Socket by socket (S x S) configuration for large-diameter lines
• Continuous service temperature limit: Up to 180 degrees Fahrenheit (82 degrees Celsius)
• Intermittent thermal tolerance: Up to 212 degrees Fahrenheit (100 degrees Celsius)
• Drainage pressure rating: Suitable for pressurized drainage applications up to 50 psi
• Chemical immunity: Unaffected by electrolysis, pitting, scaling, and electrolytic corrosion

Applications

The large-diameter P-trap is engineered specifically for chemical drainage and industrial DWV systems carrying aggressive chemical effluents. It serves as a corrosion-proof replacement for metallic drainage lines vulnerable to pitting and severe chemical attack.

• Corrosive waste drainage and chemical process pipelines
• Life sciences, biotechnology, and pharmaceutical manufacturing facilities
• Hospital, academic, and industrial research laboratories
• Food and beverage processing plants discharging hot washdowns or chemical byproducts
• Shipbuilding and marine drainage systems

Installation and jointing

The Fuseal LD P-trap is joined into piping assemblies using Georg Fischer electrofusion loose coil technology to form permanent, leak-tight joints. Electric resistance heating applied through the coil creates a controlled melt zone between the fitting socket and the pipe surface.

During the jointing process, molten plastic cools below the melt temperature to yield a joint that matches or exceeds the mechanical strength of the pipe itself. The polypropylene construction resists alkalis, alcohols, dilute mineral acids, solvents, and salt solutions, but should not be exposed to strong oxidizing acids or chlorinated hydrocarbons.
