This washer creates a cushion between the threads, reducing wear caused by direct metal-to-metal contact and protecting the threads from damage. This feature ensures that when the drain screw needs to be disassembled for maintenance, the threads remain intact and are easily reassembled. The excellent sealing performance of this washer is crucial, as the inside of the gearbox is normally filled with lubricant to lubricate the gear sets and bearings, ensuring smooth gearing and heat dissipation. The main function of this washer is to form an effective seal at the drain hole at the bottom of the gearbox when the screws are tightened, preventing the lubricant from leaking out.

Furthermore, this washer plays a vital role in preventing external impurities from entering the inside of the gearbox through the drain port. These foreign substances, if mixed into the lubricating oil, may lead to the deterioration of the lubricating oil and accelerated wear. The gaskets, on the other hand, can maintain the internal cleanliness of the gearbox and extend the service life of the gearbox and its lubrication system.
