This thermal switch fits any automotive oil or coolant circuit that has a 1/8" NPT female port, such as an inline port adapter. Once the fluid hits its set temperature, it switches on a 12-volt accessory - for example a cooling fan relay or oil pump. It's available with three presets: 82°C (180°F), 88°C (190°F) or 93°C (200°F).

Wiring this thermal switch straight to an oil pump or electric fan is not permitted - it can only be used to trigger a relay, since it isn't rated for high current draw.

This listing is for the thermal switch on its own. An inline port adapter, available with a choice of thread sizes and configurations, is listed separately.

This thermal switch fits any automotive oil or coolant circuit that uses AN threads. Once the fluid hits its set temperature, it switches on a 12-volt accessory - for example a cooling fan relay or oil pump. It's available with three presets: 82°C (180°F), 88°C (190°F) or 93°C (200°F).

Wiring this thermal switch straight to an oil pump or electric fan is not permitted - it can only be used to trigger a relay, since it isn't rated for high current draw.

This listing lets an inline port adapter be chosen from a range of thread sizes and configurations. The thermal switch on its own is listed separately.
