WESAF Pen Oil is a premium industrial-grade heavy-duty penetrating oil specially engineered to release rusted, seized, and corroded components quickly and efficiently. Formulated to meet the demanding US FED Specification VVP-216a, it delivers outstanding penetration performance by reaching deep into narrow gaps, threads, and tight mechanical clearances.
Its advanced ultra-low surface tension technology enables the oil to migrate rapidly through rust layers, breaking the bond created by corrosion, moisture, oxidation, alkali exposure, fruit acids, and electrolysis. This significantly reduces the force and time required to remove stubborn nuts, bolts, screws, fittings, and other mechanical parts.
WESAF Pen Oil not only frees jammed components but also cleans and removes accumulated tar, dirt, and carbon deposits. The specially developed blend of lightweight petroleum distillates and paraffinic oils provides excellent moisture displacement and creates a protective barrier against future corrosion, including salt-water exposure.
Designed for industrial maintenance, automotive workshops, manufacturing plants, marine applications, and general repair tasks, WESAF Pen Oil can be safely used on metals, alloys, rubber components, and most painted surfaces. Its powerful aerosol spray system with an extension tube allows precise application in inaccessible areas, ensuring minimum product wastage and maximum efficiency.
Whether it is a seized bolt during a plant shutdown, a rusted valve, a sticking hinge, or a difficult-to-remove mechanical fitting, WESAF Pen Oil provides a fast, reliable, and professional solution for maintenance engineers and technicians.
Available Packaging: 500 ml / 320 g Aerosol Spray Pack.
