Fuseal Fast-Lock pipe increaser PP S x S

  Datasheet (PDF)

The Georg Fischer Fuseal Fast-Lock pipe increaser is an engineered flame-retardant polypropylene (PPFR) mechanical joint fitting designed to expand line diameters in corrosive waste DWV drainage networks. Engineered for laboratory, industrial, and institutional chemical drainage systems, it connects socket-to-socket runs without requiring solvent cements or fusion equipment. The fitting supports an operating pressure of 35 psi and withstands intermittent fluid discharges up to 212 degrees F (100 degrees C).

Technical specifications

The Fuseal Fast-Lock pipe increaser provides immediate structural rigidity and pressure retention for vacuum and pumped corrosive drainage lines. Its mechanical joint architecture allows instant commissioning directly after mechanical torque tightening.

• Material: Flame-retardant polypropylene (PPFR)
• Connection configuration: Socket by Socket (S x S)
• Operating pressure rating: 35 psi
• Continuous operating temperature limit: Up to 180 degrees F (82 degrees C)
• Intermittent discharge temperature limit: Up to 212 degrees F (100 degrees C)
• Assembly tool requirement: 8 mm or 10 mm socket driver

Installation and jointing

Fast-Lock mechanical jointing eliminates cement cure times, chemical primers, and hazardous volatile fumes on site. The compact collar slips over the fitting hub and tightens using a standard 8 mm or 10 mm socket driver or cordless tool, requiring no pipe grooving.

Because the fitting hub shares modular dimensions with standard Fuseal electrofusion components, the design permits interchangeable collars to transition between mechanical fast-locking and electrofusion connections. The assembled line is ready for immediate pressure testing and operation once the collar hardware is tightened.

Applications

This polypropylene increaser resists attack from dilute mineral acids, alkalis, alcohols, solvents, and salt solutions without pitting, rusting, scaling, or being affected by electrolysis. It serves corrosive waste drainage across chemical process piping, hospital and university laboratories, food and beverage processing, life sciences, and marine drainage installations.
