Pump casing screws are mission-critical fasteners that define the operational integrity of fluid processing systems. They face a combination of extreme threats: intense vibration and hydraulic shock from pump operation (including cavitation), internal fluid pressure that constantly forces liquid through any thread gap, and constant exposure to the aggressive chemical environment of the process fluid. A failing casing screw is the primary pathway for high-cost leakage, pressure loss, and catastrophic unscheduled downtime.

For the engineering professional, securing these screws is the ultimate act of fluid containment and structural pressure defense.

This is the non-negotiable territory of the INCURE Re-Lok™ Red Series—featuring the B72 Heavy Duty and B77 Extreme Duty Threadlocking Adhesives. They are engineered to provide a monolithic, pressure-resistant structurethat locks the assembly and prevents fluid escape.

The Problem: Dynamic Shock Meets Pressure and Chemical Attack

Are your pump casings vulnerable to these critical threats?

• Vibrational Leakage: Constant pump vibration quickly causes fasteners to back out, creating a path for pressurized fluid to escape.
• Chemical Degradation: The process fluid (whether water, solvent, or aggressive chemical) attacks the thread interface, compromising sealants and accelerating thread corrosion.
• Catastrophic Downtime: Pump failure halts production, leading to massive financial losses and potential environmental/safety hazards.

Only a permanent, high-strength anaerobic lock can eliminate micro-movement and simultaneously guarantee a high-pressure, chemical-resistant seal.

The Position: Permanent Security and High-Resistance Sealing

The INCURE Re-Lok™ Red Series is the defined solution for permanent, high-strength applications where structural integrity and fluid containment are non-negotiable. By curing into a durable thermoset plastic, the threadlocker transforms the casing joint into a unified, pressure-resistant component that locks the assembly while filling all microscopic voids to seal against high-pressure leaks.

Here is the strategic defense the Re-Lok™ Red Series offers for pump casing screws:

1. INCURE Re-Lok™ B72 Red Threadlocking Adhesive – Heavy Duty

The High-Heat and High-Pressure Specialist.

Pumps, especially those handling hot fluids, generate significant heat. The B72 (Heavy Duty) is essential for its ability to maintain its permanent, high-strength lock under extreme operating temperatures up to 230∘C. This thermal resilience guarantees that the structural bond and the pressure seal remain intact despite continuous heat and high-pressure differentials.

2. INCURE Re-Lok™ B77 Red Threadlocking Adhesive – Extreme Duty

The Chemical Barrier for Aggressive Fluids.

The B77 (Extreme Duty) is engineered for maximum overall resistance to dynamic shear and chemical degradation. Its high viscosity formulation ensures superior gap filling for maximum resistance against rotational forces and pressure leaks, while its excellent chemical resistance creates an impenetrable, permanent seal against a wide range of aggressive process fluids, protecting the threads and ensuring reliable fluid containment.

The Strategic Payoff

By investing in the targeted, high-performance security of the INCURE Re-Lok™ Red Series, you are making a commitment to maximum process reliability. You are guaranteeing the permanent structural lock and leak-proof integrity of your pump casings, drastically reducing the risk of unscheduled downtime, environmental events, and high-cost fluid losses.
