Prevost Industrial S1 Coupler Sizes:3/8" Male 2” here in the OGDescription The Story There is no other way to put this, Prevost Couplers are quite simply the finest in the world. These are not cheap, but I think they're worth every penny. It's a bit hard to explain how these work, but they have a press button soft release.
