Key Features
The FKM Rubber Ball OEM for High Temperature Sealing is purpose-built for applications where ordinary elastomers fail under heat and chemical attack:
- Extreme Thermal Endurance - Continuous service at 220°C and intermittent exposure to 250°C, making it the go-to choice for engine compartments, exhaust systems, and industrial ovens.
- Broad Chemical Compatibility - Resists a wide spectrum of aggressive media, including aromatic hydrocarbons, chlorinated solvents, concentrated acids, and refined fuels - outperforming NBR and EPDM in corrosive environments.
- Ultra-Low Permeation - Dense fluoroelastomer structure prevents gas and vapor leakage, critical for fuel systems, vacuum valves, and pressurized chemical reactors.
- Permanent Ozone Immunity - Unlike hydrocarbon rubbers, FKM does not degrade under ozone or UV exposure, eliminating surface cracking in outdoor and high-altitude applications.
- Inherent Flame Resistance - Self-extinguishing behavior meets stringent fire-safety requirements in aerospace, marine, and industrial equipment.
- OEM-Grade Precision - Custom compound grades (standard, low-temperature, improved chemical) and tight dimensional tolerances ensure drop-in compatibility with original equipment.
Common Applications
- Automotive & Transportation - Sealing balls in fuel injectors, EGR valves, turbocharger systems, and transmission control valves.
- Aerospace & Defense - Precision spheres for hydraulic actuators, fuel systems, and environmental control units operating at altitude and temperature extremes.
- Oil & Gas - Check-valve and pump balls in downhole tools, wellhead equipment, and refinery processing units exposed to sour gas and crude.
- Chemical Processing - Sealing balls for dosing pumps, reactor valves, and solvent-handling equipment where corrosion resistance is critical.
- Semiconductor & Electronics - High-purity fluoroelastomer balls for wafer-processing valves and chemical delivery systems.
- Industrial High-Temperature Equipment - Sealing spheres for hot-oil systems, industrial ovens, and high-temperature hydraulic circuits.
Quality Assurance
- Every lot undergoes dimensional inspection, hardness testing, compression-set analysis, and chemical-resistance verification before release.
- Full material traceability and compliance documentation (RoHS, REACH, automotive/aerospace-grade certificates) available upon request.
- OEM/ODM partnerships supported with custom compounding, private labeling, and dedicated production scheduling.
