# Machine graphite plugs

Machined graphite plugs for sealing and dry lubrication; selection depends on geometry and operating conditions.

Family: Mechanical applications

## Description
Graphite plugs can support sealing or dry lubrication where their geometry and material grade match the operating conditions. Share the dimensions, load, temperature, and environment so ESGRAF can recommend and justify the appropriate material.

## Processes
- Plugging / sealing off

## Challenges
- Thermal leaks
- Deformation of metal plugs
- Contamination

## Advantages
- Thermal stability
- Custom machining
- Low adhesion on many metals

## Limitations
- Oxidation in air at high temperature without protection
- Lower mechanical strength than structural metals
- Requires grade selection by load and environment
