Product Description
Permatex Prussian Blue is a non-drying, blue oily paste used for precision fitting and inspection of machined metal surfaces. It helps identify high spots, interference points and incorrect contact areas between mating components. When the parts are assembled and moved into their working position, contact areas become visible as bright blue marks, making it easier to correct the fit.
It is particularly suitable for bearings, valves, gears, shafts and other close-tolerance or precision-machined assemblies. The compound is easy to apply, does not dry out and can be wiped clean after inspection.
Precision Surface Contact DetectionPermatex Prussian Blue 80038 excels at exposing high spots and contact patterns between machined metal components. Its vivid blue pigment clearly marks bearing surfaces, gears, and close-tolerance assemblies, allowing technicians to identify imperfections, misalignments, or uneven wear during critical inspection and fitting processes.
Ideal for Automotive and Industrial ApplicationsEngineered for versatility, this paste is tailored for tasks such as gear tooth contact evaluation, valve seating inspection, and shaft alignment in both automotive repair and industrial machinery maintenance. Its user-friendly tube design ensures precise application, while the non-drying formula supports extended evaluation and repeated adjustments.
FAQ's of Permatex Prussian Blue 80038:
Q: How do you use Permatex Prussian Blue 80038 for inspecting bearing contact?
A: Apply a thin layer of the paste on the bearing or contact surface, then assemble the parts and rotate or move them as needed. The blue pigment will transfer, indicating the specific contact areas and highlighting any high spots that may require adjustment.
Q: What are the main benefits of using Permatex Prussian Blue in mechanical applications?
A: This paste helps identify high spots and uneven contact surfaces easily, supporting precision fitting and alignment of components. It ultimately reduces wear, prevents premature failures, and ensures reliable assembly in automotive and industrial environments.
Q: When should Permatex Prussian Blue be applied during assembly?
A: It should be used during the fitting, inspection, or quality-control phases, before final assembly. The non-drying nature allows for adjustments and rechecking until optimal contact and alignment are achieved.
Q: Where can Permatex Prussian Blue be applied?
A: It is designed for machined metal surfaces such as bearings, gears, shafts, valve seats, and mating surfaces. It is suitable for use in automotive workshops, industrial maintenance, and engineering environments.
Q: What is the process for removing Permatex Prussian Blue after inspection?
A: After inspection is complete, wipe the marked surfaces with a clean cloth and an appropriate solvent such as mineral spirits or a mild degreaser to remove any residue before reassembling or finishing the parts.
Q: Is Permatex Prussian Blue safe to use, and are there any precautions?
A: While the product is generally safe for its intended use, it may cause eye and skin irritation. It is recommended to wear gloves and eye protection, and to work in a well-ventilated area. Read all safety instructions on the English and Spanish packaging before use.
