CRC Penetr8 Hi Speed Penetrant 500ml Pro Grade

Meet CRC Penetr8 Hi Speed Penetrant 500ml—a industrial-strength, low-viscosity lubricant and penetrant designed to quickly loosen and free seized, bound, or frozen fasteners. This is the fast-acting solution professionals rely on when downtime isn’t an option.

Its low surface tension formula aggressively permeates rust, scale, gum, grease and corrosion, creeping into cracks, seams, threads and joints with exceptional efficiency. After application, it leaves a thin, non-drying colorless film that continues to lubricate and inhibit corrosion, helping parts move freely long after the initial treatment.

Designed for reliability in the field, the Permastraw Dual-Action Spray System features a one-piece actuator with a two-way spray to ensure the straw stays in place, making application precise and mess-free even in tight or awkward spaces.

Key benefits

• Extreme penetrating action — high-speed penetrant that breaks through rust, varnish and gums to free stubborn fasteners.
• Faster disassembly — readily loosens rusted and corroded nuts, bolts, couplings, hinges and other frozen components.
• Independent-test proven — outperforms the competition in penetration speed and corrosion resistance.
• Corrosion protection — lubricating residue helps prevent further rust and corrosion between disassembly steps.
• Broad material safety — safe on metals and most plastics, rubbers, and paints.
• Versatile spray system — Permastraw Dual-Action Spray System keeps the straw in place for accurate, controlled applications.
• Extensive use cases — ideal for nuts, bolts, pins, screws, bushings, clips, hinges, snaps, lugs, caps, locks, washers and sliding mechanisms; also effective for cleaning concrete tools, rusted surfaces of moulds, dies and heavy tools, and for softening or removing carbon deposits.
• Industry-ready — suited to plumbing, garages, piping, construction, machine shops, heavy industry and mining environments.
• Practical size — delivered in a 500ml bottle for convenient, on-site maintenance and emergency repairs.
