Metron Marker Torque Seal
The non-toxic, highly visible, flexible, professional solution for torque strips, tamper seals and vibration aids
Torque Seal That Performs—Without the Toxic Tradeoffs
Most torque seal products were designed decades ago. Metron re-engineered the formula for modern performance, safety, and compliance.
Metron Marker Torque Seal delivers precise, highly visible torque marking and tamper detection—without the solvents, fumes, or environmental compromises of traditional products. Our non-toxic, water based formula is a premium, modern, and safer formulation.
Engineered for aerospace, electronics, and medical environments, it’s the cleaner, safer evolution of torque marking.
Precision matters in torque marking, especially in assemblies where space is limited and accuracy is critical. Metron’s precise applicator is engineered to deliver
controlled flow exactly where it’s needed, eliminating the splatter and over-application common with traditional squeeze tubes or fiber tips.
This level of control produces sharper, more consistent marks while reducing material waste and cleanup time. The outcome is a cleaner workflow overall, with faster inspections and more reliable results at every stage.
Metron Marker Torque Seal uses bright fluorescent,
UV-enhanced colors to ensure markings stand out clearly under a range of lighting conditions.

Application Guide
To use as a Tamper Seal:
- Identify the access point (such as bolt top)
- Apply ink to cover the access area
- Allow to dry completely
- Any disruption to the seal indicates tampering
To use as a Torque Stripe:
- Ambient temperature (faster with warm air)Ensure the part is properly secured
- Clean the application area if needed for best adhesion
- Apply ink across adjoining parts to create a continuous stripe
- Allow to dry at ambient temperature (warm air can speed up drying)
- During inspection, a broken stripe indicates loosening or tampering
Technical Specifications
Drying Time
Drying depends on atmospheric conditions and mark size—a small mark in warm, dry air cures faster than a larger mark in a moist environment.
Application Temperature
-20°F to 500°F
Colors Available
Multiple standard and fluorescent options, including invisible inks that fluoresce under UV light.
Industries
Widely used in aerospace, medical, electronics, data centers, and other precision-driven fields.
Appearance
Cream-like liquid (various colors)
Flash Point
Non-combustible
Resistance
Most colors resist up to 200 °C without discoloration. At higher temperatures, colors may fade, but the mark remains visible.
