Compression Coupling, Series/Model: Series 525, Nominal Size: 1/2 IN, Outside Diameter: 1.68 IN, Length: 4.13 IN, Material: Ductile Iron Sleeve, Finish/Color: Galvanized, Maximum Pressure: 150 PSI, Other Physical Dimension: 0.84 IN Pipe Outside Diameter

• A ductile or malleable iron coupling with threaded ends that seal to the pipe when turned
• Stab fit for easier installation
• Galvanized finish for additional corrosion-resistance
• Ductile or malleable iron metal parts for strength and corrosion-resistance
• May be used in most water, wastewater and industrial applications
• Wrench flats on the nuts and sleeve help with holding the coupling during tightening
• The retainer cup holds the gasket IN place and concentrates gasket compression where it is needed most
• The compression coupling may be used IN conjunction with Smith-Blair adapter gaskets to join copper pipe
• Protected gasket extends the life of the gasket and provides electrical continuity between the pipe and the coupling
• Deflection of 2 DEG per end allows for pipe movement and installation on pipe that is not perfectly aligned
