The Levelock has a ¾" NPT installation port.  While operators can use pipe adaptors to install the product on different sized ports, it’s not recommended to adapt to threads smaller than ¾". However, adapting to thread sizes larger than ¾" is fine and will not affect the performance of the Levelock. The Levelock is recommended to maintain an oil level within a reservoir. Most oil lubricated equipment is intended to be kept at a predetermined oil level, but oil levels drop over time due to evaporation, burning, and leakage. The Levelock replenishes oil as it is lost, and helps equipment maintain the ideal oil level over an extended period.
