Overview
PL-UNN-3/81/4N is the reducing coupling called out in Spectra’s Catalina 340 Connect and Z diversion assembly. The catalog specifies a Nylon coupling with 3/8-inch and 1/4-inch female pipe threads.
It joins different nominal threaded sizes. The exact catalog number is retained: this review does not turn differently formatted coupling codes into aliases.
