The Ecotech Marine Vectra Barb and Screen kit will allow your Vectra pump to use standard soft tubing such as silicone tubing. The barbed fitting will be a traditional slip fitting into the output of the Vectra pump and does require PVC solvent for worry free connection.
The included screen fitting will keep large debris that would normally cause damage and extreme wear to a pump from entering the pump. Since the screen is normally being pulled into the pump no solvent is needed to connect the screen to the pump inlet.
