REF=Reference code; DN=Fitting size mm; L=L10 mm; L1=L1 mm; D=D mm; D1=D1 mm; PN=SDR Range; FT=Fusion time seconds; CT=Cooling time minutes; WT=Theoretical weight/kg
Couplers greater than 500mm in diameter require two electrofusion cycles (dual shot), one for each end of the fitting.
Refer to the table above for the SDR rating of each individual fitting.
