Hydraulic fittings, particularly those with straight threads that secure a component (like jam nuts on adjustable fittings or straight-threaded adapters), face relentless operational stress. They are exposed to continuous system vibration, massive internal fluid pressure (often 3,000 PSI or more), and violent shock loads from pressure spikes and valve cycles. A failure here is dangerous, resulting in high-pressure fluid leaks, system failure, and potential hose whip.
Don’t let vibration or internal pressure compromise your hydraulic system’s integrity.
INCURE Re-Lok™ B43 Blue Standard Duty Threadlocking Adhesive
For hydraulic systems, which require strong anti-vibration security and resistance to aggressive fluids, but still need to be disassembled for hose or component replacement, medium strength is the critical balance. The INCURE Re-Lok™ B43 Blue is an oil-resistant, medium-strength anaerobic adhesive perfect for securing non-sealing hydraulic threads against operational pressure and shock.
| Feature & Benefit | Technical Insight for Hydraulic Fittings | Conversion Value |
| Medium Strength (Removable) | Provides secure thread locking for fasteners up to M20, preventing loosening from high-frequency vibration, while allowing for easy disassembly with hand tools. | Serviceable Security: Lock down the assembly against pressure spikes, yet permit future hose replacement. |
| Oil & Fluid Tolerance | Exhibits enhanced chemical tolerance to residual hydraulic fluids, synthetic oils, and petroleum-based fluids common in these systems. | Fluid Resistance: Ensure the lock holds tight, regardless of the challenging hydraulic fluid environment. |
| High Vibration Security | Cures into a solid plastic, filling all internal gaps between threads to prevent the severe backing out caused by pump pulsation and system shock. | Zero Loosening: Eliminate rotational creep and maintain the structural alignment of fittings and hose ends. |
| Fast Curing Speed | Reaches initial cure in 20 minutes, minimizing assembly time and allowing the system to be pressured up sooner. | Maximize Uptime: Accelerate your repair process while guaranteeing a reliable, robust final bond. |
Application Steps: Securing Hydraulic Fittings for Leak-Free Durability
Preparation (Essential): Because threadlockers require metal-to-metal contact, thoroughly clean the threads of the fitting/nut and the mating component with a degreasing solvent specifically rated for hydraulic components. Wipe surfaces until perfectly dry.
Application: Apply a continuous, thin bead of Re-Lok™ B43 Blue around the leading three-quarters of the male thread.Ensure even coverage around the circumference.
Assembly: Immediately install the fitting/nut and torque to the manufacturer’s specified value. Proper torque ensures the necessary clamping force and initiates the anaerobic cure.
Curing Time (Critical): Allow a minimum of 24 hours for the adhesive to achieve its maximum strength and fluid-resistant cure before pressurizing the hydraulic system.
Stop risking dangerous high-pressure leaks and secure your system’s connections with dependable chemical integrity.
