3. Working Principle
This flame retardant O-ring forms a reliable closed seal through elastic deformation under assembly compression, fully filling the gaps between mating parts. During operation, fluid pressure further presses the O-ring against the sealing surface to enhance leakproof performance. The special flame retardant components can isolate heat and quickly cut off flame combustion, while premium FKM material resists thermal aging and chemical erosion, ensuring continuous safe and stable sealing in complex high-risk environments.
4. Product Details
Material adopts high-performance FKM fluororubber with UL94 flame retardant compound, Shore hardness 90±5 A and fully compliant with RoHS and REACH regulations. All standard sizes comply with ISO 3601-1, and non-standard custom dimensions are available on request. Every batch completes professional flame retardant and physical property testing. Products are packed with moisture-proof packaging and outer cartons with a 24-month shelf life.
5. Application Range
Widely applied in electronic and electrical equipment, new energy facilities, high-temperature pipeline systems, power machinery, chemical installations and industrial automation devices. It is perfectly suited for confined spaces and flammable medium occasions requiring flame retardant, high temperature resistant and safety sealing.
