PG Steel Conduit Taps
Please select size & style from the pull down menu
Pg Steel Conduit Threads are manufactured in accordance with DIN 40430 STEEL CONDUIT THREAD DIMENSIONS. The Pg thread series is designed specifically for steel conduit because of the thin wall cross section of the steel conduit. The thin wall thickness requires a shorter profile thread that will not break through the outside diameter of the steel conduit during the machining process. The 80° included angle of the Pg thread form gives a shorter profile than the more common 60° included angle found in the Unified National thread series and the Metric thread series.
