T-21642 Certified® Double Acting Olson 3" Transport Vent Assembly

T-21642 Transport Vent Assembly is a certified, spring loaded and double acting, 3-A sanitary vent for safely moderating both pressure and vacuum to atmospheric conditions.

Anti-splash transport vent features a dual poppet design to prevent spills during surge and fluid leakages on inclines to further eliminate dangerous incidents such as ruptures, spills, or explosions.
