Permatex 25240 Hybrid Threadlocker Blue Pwc

Product Description

The PERMATEX 25240 is a hybrid blue threadlocker formulated for heavy-duty fastener applications on personal watercraft and marine equipment. It delivers approximately three times the holding power of standard blue threadlocker formulas while remaining removable with hand tools when service is required. The product is designed for use on fasteners ranging from 0.25 inches to 1 inch in diameter and cures to resist vibration loosening, moisture intrusion, and corrosion at threaded connections. Technicians working on PWC engines, drive systems, and hull hardware rely on this formula where higher breakaway torque is needed without committing to a permanent bond.

This threadlocker is suited for personal watercraft maintenance and repair, particularly on assemblies subject to high vibration and water exposure. Typical applications include engine fasteners, bracket hardware, and drivetrain bolts where standard-strength threadlocker does not provide adequate retention. The heavy-duty hybrid formula makes it appropriate for both professional marine service technicians and experienced PWC owners performing their own maintenance work.

Key Features

• Approximately three times the holding power of standard blue threadlocker
• Removable with hand tools after curing — no permanent lock-out
• Suitable for fastener diameters from 0.25 inches to 1 inch
• Hybrid formula resists vibration, moisture, and corrosion at threaded joints
• Designed for heavy-duty marine and PWC applications

Compatibility

Designed as an OEM-style threadlocking compound for personal watercraft and marine applications requiring heavy-duty removable fastener retention on bolts and screws from 0.25 inches to 1 inch in diameter.

Installation Notes

Apply to clean, dry, and degreased fastener threads before assembly. Ensure the mating surfaces are free of oil, water, and old thread locking compound prior to application. Allow adequate cure time before returning the assembly to service and follow all manufacturer cure guidelines. Use appropriate hand tools for removal after curing — do not apply excessive heat near fuel, electrical, or composite components on the watercraft.
