Neck Glands

Neck Glands

The hydraulic tube needs to be sealed at both ends to stop oil leaking and keep the pressure in. One end of the tube is sealed off with a base. However, the other end needs to be open to allow the rod to move in and out of the tube. At this end the tube is sealed with a neck gland that allows the rod to move in and out. The neck gland material would be chosen during design, with seals on both the rod and the tube.
