I spoke to a REAL person when I called that was polite and knowledgeable of their product. The motor seems to be great quality and it works great! Highly recommend, will buy from them again if I need air compressor parts.
1/4" FNPT coupler plug. This is an Industrial Style coupler plug. This is a high-quality steel plug made by Prevost. These plugs are made in Italy and meet the highest standards for quality and performance. These are some of the most durable, solid steel plugs that you can find. These plugs are more resistant to crushing and marring when being dropped, which is important because a quality plug can increase the life of your couplers!
