just got my new hose connectors sent from the states last week, i must say they are far Superior to any of the other types on sale for wfp, they are built of robust plastic, they are leak proof, and no dirt gets lodged in them, also a nice tight fit into a gardiners 6mm clear tubing, i can even get them with a closed valve, in either the male or female, to stop the water flow from your pumps, i have made a deal with the manufacturers
over the price of bulk buy, if anyone is interested just let me know,
