Hybrid Vault Oil Trailer Buddy
**This proprietary blend of Hybrid Lubricant is specially formulated by UFP to be used with “Vault” system. At ambient temperatures, this lubricant is thick with the viscosity approaching grease. As the bearing temperatures rise during towing, the lubricant is thermally activated, thinning out and replenishing the bearings, reducing friction and dissipating heat.
