Sight gages show coolant level without having to uncap and check the level or use a dipstick. With a threaded base, the single component gage locks tightly into position and is less prone to leakage. These Polyetherimide (PEI) sight gages have strong hydrolytic and UV stability as well as radiation resistance. PEI is inherently flame retardant and can be used for long periods at continuous temperatures up to 356° F.
