Advantages	1. Excellent resistance to mineral oils, fuels, and hydraulic fluids. 2.Good mechanical strength and abrasion resistance. 3.Cost-effective and widely available. 4.Versatile for moderate temperature applications (-40°C to +120°C).	1.Exceptional resistance to high temperatures (+200°C, up to +230°C for premium grades). 2.Outstanding chemical resistance to acids, solvents, and fuels. 3.High durability in aggressive environments (e.g., chemicals, aerospace). 4.Long service life in harsh conditions.
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.

Applications
