Piedmont Style L Grooved Coupling
Style L coupling offers favorable corrosion resistance and represents an economical choice since it is constructed from epoxy painted ductile iron. Better suited for brackish and fresh water, the Style L coupling will perform well with pressures under 300 psi. Consult Piedmont application engineering for guidance on the selection of plastic or metal alloy for your application.
Applications can impose severe-duty factors in addition to the maximum continuous operating pressure rating. These additional design requirements must be considered in selecting the appropriate Piedmont coupling.
Note: Working pressure ratings based upon generally accepted pressure piping design standards and testing in accordance with ASME Section VIII Division 1 pressure vessel test method.
300 psi (20 bar) working pressure with schedule 40s pipe with cut groove only.
