Installation is easy; you just have to remember your order of operations. It is made up of three pieces: the collar, the rubber seal, and the housing. First, you must place the collar over the cable. Then, place the seal with the long taper facing up toward the housing. The next step would be to screw the housing and collar together. Once completed, hand-tighten the luber until the seal is firmly seated and sealed against the housing. This compression-style assembly squeezes the rubber seal around the cable so the lubricant is forced through the cable.
