Keep moisture, road debris, and grime out of your Lippert power tongue jack head assembly. This black rubber side plug is the factory-correct replacement cap that seals the access holes on the jack head, protecting the internal components of your electric tongue jack and keeping it operating reliably season after season.
The Lippert 225875 is a straightforward but important maintenance item. The access holes on the tongue jack head assembly are necessary for manufacturing and service, but once your jack is in service those openings need to be sealed. An unsealed hole lets in water, road grit, and debris -- all of which accelerate wear on the jack's internal gears and motor.
This plug is made from rubber and designed to press-fit into the access port on the head assembly. It fits both the left and right side of the jack head, so a single part number covers either position. No tools are typically required -- press it firmly into the hole until it seats flush.
Engineered specifically for Lippert power tongue jack head assemblies. Press-fits securely with no hardware needed.
Flexible rubber material compresses to fill the access hole cleanly, resisting road vibration and preventing accidental dislodging.
One part number covers both the left-side and right-side access holes on the jack head assembly -- no separate part needed per side.
No special tools or adhesives required. Press the plug into the hole until seated flush with the housing surface.
A missing side plug on a tongue jack head assembly is a small problem that can become an expensive one. The electric motor, drive gears, and worm drive inside the jack head are not designed to tolerate prolonged moisture or dirt intrusion. Even a single season of highway driving without this plug in place can pack debris into the housing.
This plug is designed for Lippert electric power tongue jacks that use a bolt-on head assembly style. Lippert produces tongue jacks across a wide range of capacities (3,500 lb. to 5,000 lb. class and beyond), and many share this same head assembly format with the same access hole diameter. If your current plug is cracked, missing, or does not seat firmly, part number 225875 (vendor reference 71-5613) is the correct factory replacement.
