Green Sleeve Retainer

The Green Sleeve Retainer by PERMATEX is a high-temperature thread locker engineered for professionals who demand reliable fastener security in extreme thermal environments. This 36 ml bottle delivers precision thread-locking performance for machinery, automotive assemblies, and tactical equipment where vibration, heat cycling, and mechanical stress threaten bolt integrity. Designed for technicians and field operators who cannot afford fastener failure, this product prevents loosening without permanent bonding, allowing future disassembly when required.

PERMATEX's high-temperature formulation withstands sustained heat exposure that would compromise standard thread lockers, making it ideal for engine blocks, exhaust manifolds, and load-bearing connections. The sleeve retainer technology provides medium strength—sufficient to lock fasteners against vibration while remaining removable with hand tools under normal conditions. Applied directly to clean threads in minimal quantities, the product cures anaerobic ally (without air exposure), creating a resilient polymer matrix that fills micro-voids and distributes clamping loads evenly across the threaded interface. The 36 ml bottle format ensures controlled dispensing and extended shelf life for workshop and field kit applications.

This thread locker serves military armorers, automotive technicians, equipment maintenance teams, and tactical operators securing critical fasteners in small arms, optics mounts, and mission-critical gear. Ideal for applications where fasteners must remain secure through recoil, temperature fluctuation, and extended field use—yet remain serviceable without destructive removal. Best results are achieved on fasteners ranging from 1/4" to 3/4" diameter; ensure surfaces are clean and dry before application. Compatible with steel, stainless steel, and most metal fasteners where thermal cycling and vibration present genuine risk of loosening.
