Matco-Norca’s Swage Concentric Nipples are reducers for high-pressure piping systems that contain a bore matching that of the pipe they are fitted to. They are available in Schedule 80 and Schedule 40 sizes: 1/2” to 4” and 2” to 4”, respectively. They are fully traceable back to the production mill (mill test results are available) and conform to MSS SP-95, ASME B1.20.1 and ASME B36.10M (for wall thickness) standards. Swage nipples come in standard and XH concentric configurations.  PM1014_Products_PVF_Matco-Norca-SwageNipples_Bull-Plugs_300.jpg
