Fuseal Fast-Lock reducer bushing PP SPG x S

  Datasheet (PDF)

The Georg Fischer Fuseal Fast-Lock reducer bushing is an engineered flame-retardant polypropylene fitting designed for industrial and laboratory corrosive waste drainage systems. Featuring a spigot by socket (SPG x S) configuration, the reducer bushing transitions pipe diameters within the compact Fast-Lock mechanical joint layout. It provides reliable service for chemical DWV applications requiring rapid mechanical assembly and resistance to intermittent pressures up to 35 psi.

Technical specifications

The Georg Fischer Fuseal Fast-Lock reducer bushing provides pipe size transitions in corrosive waste drainage lines while maintaining full pressure containment under vacuum and pumped discharge cycles.

• Connection configuration: Spigot x Socket (SPG x S)
• Operating pressure rating: 35 psi for Fast-Lock mechanical joint assemblies
• Continuous operating temperature: Up to 180 degrees Fahrenheit (82 degrees Celsius)
• Intermittent discharge temperature: Up to 212 degrees Fahrenheit (100 degrees Celsius)
• System service: Gravity, vacuum, and pumped laboratory DWV applications

Materials and standards

Manufactured from flame-retardant polypropylene, this fitting provides long-term resistance against chemical corrosion, scaling, and electrolytic deterioration. The material is formulated to withstand contact with dilute mineral acids, alkalis, alcohols, solvents, and salt solutions without pitting or degradation.

For above-ground installations, the integrated pigmentation shields the thermoplastic structure from ultraviolet radiation and is heat-stabilized to handle high-temperature corrosive effluents. Polypropylene remains chemically stable under diverse laboratory environments, being vulnerable only to strong oxidizing acids and specific chlorinated hydrocarbons.

Installation and jointing

The Fast-Lock mechanical joint design enables clean, immediate assembly in restricted spaces without requiring solvents, open flames, or grooving tools.

Joint compression is completed using an 8 mm or 10 mm socket driver on the mechanical collar. Because the system eliminates chemical bonding compounds, there are no cure times or toxic fumes, allowing lines to be pressure tested immediately upon completion. The fitting is also modularly compatible with Georg Fischer Fuseal electrofusion collars for adaptable installation layouts.
