The ND INDUSTRIES 12535 is a removable-grade anaerobic thread sealant and threadlocker formulated to lock and seal threaded fasteners against loosening caused by shock and vibration. Supplied in a 35 ml bottle, this product cures in the absence of air between mating metal surfaces, creating a secure bond that outperforms mechanical alternatives such as lock washers and bevel washers. It also prevents rust-lock and stops fluid leakage at threaded connections. Licensed tradespeople working in HVAC, plumbing, and general mechanical service commonly specify removable-grade threadlockers where future disassembly is required.
This product is suited for residential and light commercial applications where threaded fasteners are exposed to ongoing vibration or thermal cycling. Typical uses include securing bolts, screws, and fittings on equipment frames, pumps, motors, and piping assemblies. The removable grade allows fastener removal with standard hand tools, making it appropriate for components that require routine maintenance access.
Designed as an OEM-style removable threadlocker for use on standard threaded metal fasteners in HVAC, plumbing, and mechanical equipment assemblies.
Applied by licensed HVAC technicians, plumbers, and mechanical contractors during assembly or reassembly of threaded fasteners. Clean and degrease mating threads before application to ensure proper curing. Apply a consistent bead to the fastener threads, assemble immediately, and allow adequate cure time before returning the assembly to service. Follow applicable codes and the manufacturer guidance for cure time prior to pressurizing any fluid system.
