Review: Use These ConnectorsTo Repair Your Yard Vacuum Hose... Rather Than Purchasing a New One! - I used these duct connectors to connect 2 pieces of plastic hose that connected a mower deck to to a pull behind leaf-vacuum trailer. The 6in hose ends slipped onto the steel connector and I secured them with stainless steel hose clamps. These connectors saved me from having to purchase a new hose. I will get another mowing season out of my old vacuum hose! Saving me nearly sixty dollars, after purchasing the connectors and clamps.
Review: Works as advertised. Perfect. - Great quality product, well made, quality material, perfect craftsmanship. The edges are tapered, making insertion in a flex duct a simple task. The quality construction made installing hose clamps no problem. I would say that I would buy thos product again, I already have for another project. You can't go wrong with this connector.

## Features

- The male fit coupler is a two-hole - 2 way connector. Outside Diameter 3.9" Inches.
- Made out of quality galvanized steel, it is a material with high strength, good toughness and is long lasting.
