PERMATEX NON-DRYING PRUSSIAN BLUE FITTING COMPOUND .75 FL OZ

Permatex is a well-known name for dependable automotive chemicals, and their Prussian Blue Fitting Compound is no different. This .75 fl oz tube is designed for precise application, making it ideal for tasks where accuracy is key.

Prussian Blue is a traditional marking compound used to identify high or low spots on mating surfaces. When you apply a thin layer to one surface and mate it with another, the compound transfers to the high points on the mating surface. This allows you to quickly see where adjustments are needed for a perfect fit, especially in critical areas like bearing caps or valve seats. The non-drying formula means you have ample time to make the necessary adjustments without the compound hardening prematurely.
