Fuseal Union PPFR x PPFR PPFR Nut S x S

  Datasheet (PDF)

The Georg Fischer Fuseal flame-retardant polypropylene (PPFR) union provides a robust, demountable connection engineered for corrosive chemical waste, laboratory drainage, and industrial DWV piping systems. Built with socket-by-socket (S x S) fusion ends and an integrated threaded PPFR union nut, this fitting facilitates effortless separation of pipe runs, enabling inspection, line maintenance, and equipment isolation without destructive pipe cutting. Each socket terminal integrates with the Fuseal electrofusion jointing method, utilizing plastic-coated electrical resistance coils to create a homogeneous, leak-tight fusion zone that rivals the host pipe in structural strength. To maintain fluid containment across severe service conditions, the internal sealing interface accepts precision elastomeric O-rings in either chemically resilient EPDM or high-grade FKM fluorocarbon elastomers, delivering comprehensive resistance to corrosive alkalis, acids, salts, and active solvents. Designed to perform reliably under demanding operational profiles, the fitting withstands continuous media service temperatures up to 180 degrees Fahrenheit (82 degrees Celsius) and handles intermittent chemical effluent discharges reaching 212 degrees Fahrenheit (100 degrees Celsius). The assembly complies with low-pressure drainage and vacuum operations rated up to 50 psi, providing exceptional dimensional stability, zero scaling or pitting, and total immunity to electrolytic corrosion. Stabilized against heat and ultraviolet degradation for exposed above-grade installations, the union serves as a vital transition in life sciences, healthcare facilities, academic research labs, and demanding chemical processing networks.
