A pour cap for a fluid container includes a cap body, a gasket mounted to the cap body, and a threaded ring attached to the cap body. The cap can be positioned on the container in a closed position wherein the container is hydraulically sealed with a high pressure seal, or in an open position wherein fluid flow occurs through flow passages on the gasket and the cap body with first and second low pressure seals preventing unwanted leakage between joining parts on the cap. A method for sealing and pouring a fluid from a container includes the steps of providing the pour cap with the cap body, the gasket and the threaded ring; tightening the cap body to a closed position wherein deformation of the gasket seals the container with a high pressure seal; and then rotating the cap body to an open position wherein the gasket returns to an essentially undeformed state to form a fluid flow passage, while providing first and second low pressure seals for preventing unwanted fluid flow through the cap body and the threaded ring.
