Permatex 26210 Permanent Strength Threadlocker Red 10 Ml

Product Description

The PERMATEX 26210 is a permanent, high-strength red threadlocker formulated for fasteners ranging from 3/8 inches to 1 inch in size. Applied before assembly, it cures to resist heavy shock, vibration, and extreme chemical or environmental exposure. The gel formula stays in place during application, making it well-suited for overhead and vertical fastener work. Once cured, the bond is permanent - localized heat and hand tools are required to break the joint. Licensed mechanics, industrial maintenance technicians, and HVAC or equipment service pros use this product when torque-critical fasteners must not loosen under operating stress.

The 26210 is used in heavy-duty fastener applications where vibration or thermal cycling would otherwise back out threaded hardware. Typical uses include assembly with air tools, cylinder block bolts, ring gear bolts, and transmission shaft bolts. It is OEM-specified for applications demanding a permanent bond that outlasts service intervals. The 10 ml tube format is suited for single-job or low-volume shop use.

Key Features

• Permanent, high-strength cure resists shock, vibration, and extreme chemical or environmental conditions
• Gel formula prevents migration and runoff during application
• Fits fastener sizes from 3/8 inches to 1 inch (10 mm to 25 mm)
• OEM-specified for critical threaded fastener assemblies
• Disassembly requires localized heat plus hand tools - prevents accidental loosening
• 10 ml tube size for targeted, controlled dispensing

Compatibility

Designed for threaded fasteners between 3/8 inches and 1 inch in diameter. Suitable for cylinder block bolts, ring gear bolts, transmission shaft bolts, and similar high-stress fastener assemblies in mechanical and industrial applications.

Installation Notes

Clean and degrease mating threads before applying the threadlocker to ensure proper adhesion and full cure strength. Apply a small, controlled amount to the fastener threads immediately before assembly and torque to specification using appropriate hand or air tools. Because the cured bond is permanent, plan for the use of localized heat - typically from a heat gun or torch - combined with hand tools when disassembly is required. This product is intended for professional use in environments where permanent fastener retention is required.
