The method of installation and the possible groove types for rod seals depend on the materials, seal design and ratio between the diameter and cross-sectional height. PTFE or other harder materials may require a smaller radial depth S or even open grooves.
Installing rod seals in closed grooves
Rod seals can often be installed into closed grooves through carefully bending the profile similar to a kidney shape and then inserting it into the groove. It is very important to avoid sharp bending.
Thin and flexible profiles can be installed by hand (fig. 1 and fig. 2 ). Installation tools for TPU rod seals help to install profiles of greater section thickness (fig. 3, fig. 4, fig. 5, fig. 6, fig. 7 and fig. 8). After installation, the seal may need to be reshaped to a round form using a cone-shaped tool.
