North American Trailer Dealers Association 2019 Product of the Year -

This cap was created to solve the age-old trailer issue of constantly broken fragile plastic oil caps that:

  • Cost you money replacing multiple caps year over year
  • Cost you time & labor to stop, maintain, and replace broken caps
  • Cost you a customer AND the job if your trailer breaks down due to leaking lubrication

Revolutionary Features:

  • Magnetic vent plug that captures metallic particles & debris to preserves internal axle components and prevent bearing failure
  • Heavy duty aluminum alloy body protects from exponentially more external damage to eliminate replacement frequency & decrease downtime
  • Zerk fitting port allows for easy conversion of oil bath hubs to grease packed hubs
