Application	Hydraulic systems; Fuel systems; Automotive engines; Oil pumps; Other general industrial; equipment with oil-based media.	High-temperature environments; Automotive engines; Turbochargers, gaskets; Chemical processing plants; Aerospace seals; Applications of aggressive chemicals or fuels.
Storage& Maintenance	1. Regular Inspection: Periodically check the O-ring for signs of wear, such as abrasion on the surface, and aging, which may present as cracking, hardening, or discoloration.  2. Timely Replacement: Replace O-rings immediately if they are damaged, deformed, or show signs of aging. A defective O-ring can no longer ensure proper sealing performance. 3. Exposure Avoidance: Prevent O-rings from being exposed to harsh environments for extended periods.
