Overview
Dykem® Cross Check™ Torque Seal Tamper-Proof Indicator Paste is a green, oil-based paste supplied as part number 83315. Applied as a thin bead across a fastener and adjacent surface, the material dries to form a visual seal that will crack or break if the fastener moves due to vibration or tampering. The product adheres well to metal and other substrates, provides high visibility (including UV fluorescence), and serves as a simple method for inspection, quality control and warranty protection.

Features & Benefits

- High visibility: Bright green in ambient light and fluorescent under UV for easy inspection
- Excellent adhesion: Sticks securely to metal and other substrates to maintain marking integrity
- Warranty protection: Provides a visual record to detect unauthorized disassembly or movement
- Durable performance: Withstands vibration and temperature without premature failure
