What the AI looks for in Magnetic Seals
- Which magnetic seal you need
- Door gasket (magnetic strip in a flexible PVC profile) for refrigeration and enclosures, or a magnetic-fluid rotary feedthrough for vacuum and gas sealing These products share the name but have nothing else in common.
- Gasket: OEM part number or profile
- Match the cabinet maker's gasket part number. Otherwise match the mounting style (push-in dart, screw-in or snap-in) and the profile cross-section. The wrong retention style will not fit the door channel, however close the dimensions are.
- Gasket: dimensions
- Measure the outside dimensions of the old gasket's frame, corner to corner, and check whether it is sold as a moulded frame or as cut strip Moulded-corner frames seal far better than strip joined at the corners.
- Feedthrough: vacuum and speed rating
- Match the rated pressure differential, shaft speed and operating temperature to the process The magnetic fluid can fail or outgas if it is overheated or overspeeded.
Brands that matter
- Ferrotec: Ferrofluidic vacuum rotary feedthroughs and magnetic fluid seals.
- Rigaku: Magnetic fluid rotary seals for vacuum equipment.
What to avoid
- Generic 'universal' fridge gaskets cut to length for commercial reach-ins
- Buying a door gasket without confirming the mounting style
- Running a magnetic fluid seal above its rated temperature
Questions
Will a new magnetic gasket fix a door that won't seal?
Only if the gasket is the fault. Check door alignment and hinges first, because a sagging door will not seal even with a new gasket.
