Several lines of tubular heater seals not only meet the UL 197 standards, but also meet IEC-IS 60335-2-47 standards. In both of these standards, resistance to moisture ingress for cold resistance inspection testing is paramount, as well as the ability to control leakage current during operation. The V Seal, V Seal Plus, A Sea,l and RX Seal are designed as low-cost alternatives to a hermetic seal, for long-term storage in high humidity environments. The products must meet stringent international import standards for leakage current, which can be affected by moisture absorbed during transport and extended periods of storage.
