Frequently Asked Questions
Q: Is this O-ring compatible with Thermo King Precedent units?
A: Yes. The AS568-213 size and EPDM material provide a precision fit and reliable sealing for Precedent-series components and other Thermo King refrigeration units.
Q: What fluids and conditions suit EPDM material?
A: EPDM resists ozone, steam, water, alcohols, ketones and dilute acids and alkalis, making it ideal for refrigeration system seals. Avoid prolonged exposure to petroleum-based oils and greases that degrade EPDM.
Q: How often should O-rings be inspected or replaced?
A: Inspect O-rings at regular service intervals and during any service that opens sealed connections. Replace if compression set, cracking, or surface damage appears to preserve temperature control and prevent leaks.
Q: Can this part support Smart Reefer or telematics-enabled units?
A: Yes. Maintaining proper seals with OEM Thermo King O-rings supports the temperature stability required by Smart Reefer SR-4 monitoring and telematics systems.
