The Sur-Lock Valve Cover System was designed to eliminate the unsafe practices of using cheater pipes and sledge hammers to tighten and loosen valve covers. In current practice, one rig hand will hold a pipe in the valve cover holes and another will swing a large sledge hammer at the pipe in order to loosen or tighten the assembly. The new Sur-Lock system eliminates this unsafe practice and radically decreases the time it takes to remove valve covers, and replace valves and seats. The new system requires no special tooling and weighs about the same as a conventional valve cover assembly. With the use of an impact wrench or just a torque wrench, the valve cover can be removed or replaced with minimal safety risk.
