Fuseal Cap S PP

  Datasheet (PDF)

The Georg Fischer Fuseal socket cap provides a robust, leak-free pipe termination for industrial DWV and corrosive chemical drainage networks. Designed for high-capacity polypropylene special waste lines from 8 inches to 12 inches, this fitting isolates piping branches with maximum chemical and temperature resistance. It delivers reliable performance across harsh laboratory, process, and industrial drainage installations.

Technical specifications

The Georg Fischer Fuseal socket cap terminates large-diameter polypropylene chemical waste piping runs with a permanent, secure joint. Engineered for atmospheric or pressurized special waste systems, the component maintains structural and leak-tight integrity under continuous high-temperature effluent service.

• System rating: Rated for non-pressure gravity flow and pressurized drainage applications up to 50 psi.
• Thermal threshold: Continuous service operation up to 180 degrees Fahrenheit (82 degrees Celsius) with intermittent discharge tolerance up to 212 degrees Fahrenheit (100 degrees Celsius).
• Connection geometry: Socket configuration (S) engineered for large-diameter electrofusion loose coil or butt fusion jointing.
• Chemical immunity: Completely impervious to pitting, scaling, rusting, and electrolytic degradation caused by chemical waste streams.
• Environmental stability: Heat-stabilized composition with integrated UV protection for dependable indoor and above-ground outdoor service.

Materials and standards

Manufactured from chemically inert polypropylene, this component is available in both flame retardant (PPFR) and non-flame retardant (PPNFR) formulations. The formulation withstands harsh chemical attack across a wide spectrum of alkalis, alcohols, acids, salt solutions, and solvents.

The material resists dilute mineral acids and aqueous salt formulations that typically degrade metallic drainage networks. It is attacked only by strong oxidizing acids and softened by specific chlorinated hydrocarbons and organic solvents. Fuseal polypropylene compounds incorporate specialized UV inhibitors and heat stabilizers to prevent polymer degradation under sun exposure in exposed, above-grade pipe runs.

Applications

This socket termination fitting is engineered for special chemical waste drainage (DWV) across severe industrial, research, and institutional settings. It provides dependable isolation and dead-end closure in corrosive gravity and low-pressure drainage lines.

Standard installation environments include life science laboratories, hospital research facilities, university chemistry departments, chemical processing plants, food and beverage manufacturing facilities, and marine or shipbuilding effluent systems. It frequently serves as a direct, corrosion-proof alternative to failing cast iron, silicon iron, and alloy metal systems handling multi-component acid, solvent, and caustic mixtures.
