Penetrating oil PRF PFR 520 ml – penetrating lubricant for loosening rusted fasteners

Penetrating oil PRF PFR 520 ml is an aerosol-formulated penetrating lubricant designed to loosen seized, rusted or corroded fasteners and small components. The spray delivers a thin, low-viscosity film that works its way into threads, seams and joints to reduce friction and help break corrosion bonds. Intended for workshop, maintenance and DIY use, this product supports easier removal of bolts, nuts, hinges and fittings and provides short-term protection against further rusting.

Advantages

The PRF PFR penetrating oil provides rapid capillary action to reach tight clearances and threaded connections. Its low-viscosity formulation allows deep penetration into corroded areas, while the aerosol delivery ensures targeted application in hard-to-reach spots. The product helps reduce the force required to loosen fasteners and limits additional damage during disassembly. It also leaves a thin protective layer that slows down new corrosion immediately after treatment.

Suitable for

• Loosening rusted bolts, nuts and screws
• Releasing seized hinges, latches and fittings
• Maintenance of automotive, industrial and household fasteners
• Preparation for disassembly during repair and refurbishment tasks

Key specifications

• Form: aerosol spray, 520 ml container
• Function: penetrating lubricant and corrosion loosen-er
• Application: local spray for threads, joints, hinges and fittings
• Viscosity behavior: low-viscosity for capillary penetration
• Protection: leaves thin film to reduce immediate re-corrosion

How to use

Shake the can well before use. Hold the aerosol nozzle approximately 10–20 cm from the surface and apply a short, targeted spray to the corroded fastener or joint. Allow the oil time to penetrate; waiting a few minutes can improve loosening action, and for heavily corroded parts, repeat application and allow longer dwell time. After penetration, attempt to loosen the fastener with appropriate tools. Wipe away excess product and, if needed, clean the area before reassembly.

Usage recommendations

Use in a well-ventilated area and avoid open flames during application. Do not spray onto hot surfaces or near ignition sources. Test compatibility on painted or plastic surfaces in an inconspicuous spot before extended use. Store the aerosol upright at moderate temperatures and keep out of reach of children.
