An oral inflation and relief tube for connection to an inflatable article. The oral inflation and relief tube includes an elongated tube having an oppositely positioned first opened end and second opened end, with a flanged opening positioned therebetween at ninety degrees for connection to the inflatable article. The flanged opening comprises a mounting flange and boss integrally formed through a wall of the elongated tube. The oral inflation and relief tube also includes an inflation valve sealingly positioned within the first opened end as well as a relief valve sealingly positioned within the second opened end. The elongated tube comprises an in-line configuration. The inflation valve and the relief valve and the tube comprise a generally-cylindrical configuration with a common axis, with the boss positioned substantially adjacent to the second opened end away from the first opened end such that when the mounting flange of the flanged opening is connected to the inflatable article, the in-line configuration of the elongated tube lies substantially parallel to the inflatable article. This permits the first opened end to be grasped and rotated about the boss and orally inflated. The inflation valve and the relief valve each have a coil spring with the coil spring of the relief valve having a high cracking pressure than the inflation valve.
