OLI fluid level gauge is made of polyamide. It can resist the acidity and alkalinity of oil. It would be damaged by alcoholic liquid.
Max. working temperature: 105ºC (221ºF) at normal pressure The recommended torque is 8 Nm when tightening the oil level indicator.

The material of the body is polyamide and the seal is N.B.R synthetic rubber.

Max. working temperature: 105ºC (221ºF) at normal pressure
The recommended torque is 10-12 Nm when
tightening the oil level indicator.

Oil indicator is transparent because of a special polyamide material. It improves appearance and visibility.

Resistant to oil solvents, grease and other chemical agents. Max. working temperature：105 ºC (221 ºF) at normal pressure
