China Wood Oil (Tung Oil, Wood Oil) Compatibility with Rubber O-Rings & Gaskets

China wood oil, also known as tung oil or wood oil, is a natural drying oil derived from the seeds of the tung tree and widely used in wood finishes, varnishes, and protective coatings. When exposed to air, tung oil polymerizes to form a hard, water resistant film that protects wood surfaces while enhancing their appearance. In equipment and systems where tung oil is present, O-rings, rubber seals, gaskets, and plastic components should be evaluated for chemical compatibility to ensure reliable sealing and prevent swelling of certain rubber materials. Proper handling and storage practices help minimize irritation risks and maintain product quality.
