Oil plug

An oil plug is a critical sealing component widely used in industrial machinery, automotive engines, construction equipment, and outdoor power equipment. It is primarily installed on the oil pan or oil reservoir of equipment to securely seal the lubricating oil within the system, preventing leakage during operation.

During routine maintenance, the oil plug can be easily removed to drain old or contaminated oil, allowing replacement with fresh oil and ensuring smooth operation of internal components such as gears, bearings, and pistons.

Oil plugs are manufactured from high-strength materials such as carbon steel, stainless steel, or brass, and feature precision-threaded designs to match various equipment ports. Some high-performance models include washers or sealing rings to enhance sealing performance and withstand demanding operating conditions, including high temperatures, heavy loads, and vibration.
