These OEM-matched rubber plugs seal the manual override crank opening on top of your Lippert electric trailer tongue jack, keeping out road grime, moisture, and debris when the override isn't in use. A small part that prevents a big headache -- one missing plug can allow dirt into the jack mechanism over time.
The Lippert 72-3404 is a direct-fit replacement pair of rubber plugs designed specifically for the Lippert 285318 electric trailer tongue jack. The crank opening on top of the jack head is there for manual override in case of motor failure or power loss -- but when that crank handle isn't inserted, the opening needs to be covered. These plugs do exactly that.
At just 0.08 lbs. for the pair, they're easy to keep as spares in your toolbox or parts bin. If an original plug cracked, went missing during transport, or was damaged during a manual override operation, this pair gets you back to a properly sealed jack head.
Engineered to fit the crank opening on the Lippert 285318 electric tongue jack head -- no trimming or modification needed.
Includes 2 rubber override plugs per order. Keep one installed and one as a backup spare.
Flexible rubber material allows easy insertion and removal while maintaining a snug seal in the jack's crank port.
Backed by Lippert's limited 1-year manufacturer warranty for defects in materials and workmanship.
Lippert power tongue jacks include a manual override port -- a hex or square crank socket on top of the jack head -- so you can operate the jack by hand if the motor or battery fails. When that port is not in use, the rubber plug seated in it keeps out water, dirt, and road debris that could work their way into the upper jack assembly during travel.
Over time, original plugs can crack from UV exposure, harden and fall out, or simply go missing when the manual override is used and the plug isn't immediately replaced. A missing plug on a tongue jack that travels hundreds of miles across wet or dusty roads is an invitation for premature wear or corrosion inside the mechanism.
These plugs are confirmed to fit the Lippert 285318 electric trailer power tongue jack. The 285318 is a widely used Lippert power tongue jack found on a broad range of travel trailers and fifth wheels from major manufacturers including Forest River, Keystone, Grand Design, and Coachmen, among others.
