V2B Gaskets offer vacuum and pressure relief for tank venting when airborne particulate removal is required. Using a 200 mesh screen combined with a 14 mesh screen of scintered construction, we have created a cost effective alternative to expensive vacuum breakers and venting systems. Installation can be horizontal, vertical or in single or multiple port configurations (i.e. manifolds) without special fabrication or expensive tooling. The V2B screen will fit perfectly into the ID of a sanitary pipe and can be used for inflow fluid conditioning filtration.
