Aircraft maintenance is built on attention to detail. Every fastener, inspection point, and maintenance action must be verifiable, traceable, and easy to inspect. That’s where Cross-Check® Torque Seal has earned its place as one of the most widely used visual inspection products in aviation and industrial maintenance.
What Is Torque Seal?
Cross-Check Torque Seal is a tamper-evident indicator paste designed to provide a clear visual reference that a fastener has been properly tightened and inspected.
Once applied across a fastener and adjacent surface, Torque Seal creates a visible mark that immediately indicates whether movement has occurred.
If the fastener loosens, shifts, or is tampered with, the mark breaks, making discrepancies easy to identify during routine inspections.
Why Use Torque Seal?
During maintenance inspections, technicians often need a quick way to verify that critical fasteners remain secure.
Torque Seal provides:
- Immediate visual inspection
- Tamper indication
- Fast identification of fastener movement
- Reduced inspection time
- Improved maintenance confidence
Rather than rechecking every fastener manually, maintenance personnel can visually confirm the integrity of previously verified connections.
Common Aviation Applications
Cross-Check Torque Seal is commonly used on:
- Engine mounting hardware
- Propeller assemblies
- Brake systems
- Flight control linkages
- Landing gear components
- Avionics installations
- Ground support equipment
Its highly visible marking makes it ideal for both scheduled inspections and operational checks.
Available in Multiple Colours
One of the advantages of the Cross-Check range is the availability of multiple colours.
Different colours can be used to:
- Differentiate inspection stages
- Identify maintenance teams
- Highlight specific systems
- Improve visibility on various surfaces
At Comet Aviation Supplies, Cross-Check Torque Seal is available in:
- Pink
- Blue
- Red
- Yellow
- Green
- Orange
- White
- Grey
This flexibility allows maintenance organisations to create their own visual inspection procedures and colour-coding systems.
Built for Harsh Environments
Aircraft operate in demanding conditions that expose components to:
- Vibration
- Temperature variation
- Moisture
- Fuel and lubricant exposure
- Daily operational stress
Cross-Check Torque Seal is formulated to remain visible and effective in challenging maintenance environments, helping technicians quickly identify any movement or disturbance.
A Simple Product That Improves Safety
Not every maintenance tool needs to be complicated.
Sometimes a simple visual indication can provide significant benefits by making inspections faster, more efficient, and easier to standardise across a maintenance operation.
For maintenance organisations, flight schools, aircraft owners, and AMOs, Torque Seal adds an extra layer of confidence that critical fasteners remain exactly where they should be.
