In most cases rod extension is required to compensate for the boot compression. Complete the rod boot order form and return with cylinder specifications to your FABCO-AIR distributor. When ordering a rod boot without a cylinder, complete the rod boot order form and return to your FABCO-AIR distributor. Standard rod boot mounting uses a round cuff that mounts to the cylinder's retainer ring but there are some exceptions. (See chart at right) The purpose of a drain-back gland is to prevent residual oil which has bypassed the rod seal from reaching the rod wiper. The image that is shown represents a standard seal configuration, however, there are multiple types of seal configurations that can incorporate a drain-back gland design. Fabco recommends piping the drain-back port, which is commonly a 1/8 NPTF, to the hydraulic fluid holding tank. Standard drain-back port position is #3 although this may vary based on application. Review page 57 to reference drain back port location options. Please contact Fabco for more details on other possible seal & drain-back gland options/configurations.
