The Isolation Couplings (ISO) are available in three sizes both grooved and threaded. These couplings are designed for electrical isolation with a Dielectric Strength of 42 kV and will also help in the reduction of vibration and noise from being transmitted to the cab. The maximum operating temperature for these Isolation Couplings is 225º F (107º C).

All Isolation Couplings are designed to meet or exceed ASME A17.1/CSA B44.
