Abstract: A simple venting device for trapped gas pockets in hydraulic systems is inserted through a small access passages, operated remotely, and removed completely. The device comprises a small diameter, closely wound coil spring which is pushed through guide means which is temporarily inserted in the access passage. The guide has a central passageway which directs the coil spring radially upward into the pocket so that with the guide properly positioned for depth and properly oriented, the coil spring can be pushed up into the top of the pocket to vent the same. By positioning sealing means around the free end of the guide, and using operating means, the spring and guide means are removed and the passage is sealed.
