Initially, I just purchased online, but ordered the wrong part. I called and talked to a real person, who helped me order the correct part and offered a reasonably priced return shipping label. That was a welcome change from other recent online purchase interactions.
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!
