Nd Industries 21330 Vibra-tite VC-3 Thread Sealant 1 Oz

Product Description

The ND INDUSTRIES 21330 is a thread-locking and sealing coating designed for threaded fasteners in mechanical and trade applications. It uses an acrylic resin blend that works on the principle of friction through viscosity, creating resistance that prevents fasteners from loosening under prolonged shock and vibration. The coating also acts as a dam between mated threads to resist fluid and gas leakage at fastening points. At 1 oz, it is sized for field service and bench work. A key advantage is reusability: treated fasteners can be removed and reinstalled five or more times without reapplication.

This thread sealant and locking coating is suited for use in HVAC, plumbing, electrical, and mechanical systems where threaded fasteners are subject to vibration, thermal cycling, or pressure. It is appropriate for residential and light commercial applications. Service technicians, pipefitters, and maintenance professionals apply it during assembly or reinstallation of hardware such as panel fasteners, pipe fittings, and equipment mounting hardware.

Key Features

• Acrylic resin formula creates friction through viscosity to lock threaded fasteners
• Resists loosening under extreme shock and prolonged vibration
• Seals between mated threads to limit leakage at fastening points
• Reusable on treated fasteners five or more times
• Compact 1 oz size suited for field service kits and bench use

Compatibility

Designed as an OEM-style thread-locking and sealing coating for use on standard threaded fasteners across mechanical, HVAC, plumbing, and electrical trade applications.

Installation Notes

Applied by licensed technicians and service professionals during fastener assembly or reinstallation. Clean and degrease mated threads before application for best adhesion. Follow all applicable codes including NEC and IFGC guidelines where fastener integrity is required for system safety. Allow adequate cure time before returning fasteners to service load.
