Flange Gaskets: Your Guide to Optimal Selection and Performance
Choosing the right sealing solution for your piping systems requires understanding material properties, application requirements, and industry best practices.
As sealing specialists with decades of combined experience, we understand that proper gasket selection impacts not just system efficiency but also workplace safety and maintenance costs. Let’s examine the three primary gasket categories and their ideal applications.
1
Non-Metallic Gaskets: The Cost-Effective Workhorse
Key Advantages
- Excellent chemical resistance profile
- Easy installation and compression
- Budget-friendly for standard applications
Our Recommended Uses
- Water treatment facilities
- Low-pressure chemical processes
- HVAC and plumbing systems
Note: While economical, these gaskets have temperature limitations (typically ≤250°F/121°C) and shouldn’t be used in high-pressure scenarios.

Coated Non-Metallic Gaskets: Enhanced Protection
Our clients in chemical processing often choose coated gaskets when they need:
- Better resistance to aggressive media
- Extended service life in moderate conditions
- Improved sealing without metal components
Pro Tip: The coating thickness significantly affects performance—we recommend 0.5-1.0mm for most industrial applications.

Semi-Metallic Solutions: When Performance Matters
Spiral Wound Gaskets
In our experience working with oil refineries and power plants, these gaskets deliver exceptional results because:
- The metal winding provides spring-like compression
- Filler materials adapt to flange imperfections
- They handle thermal cycling better than solid gaskets
Metal Jacketed Gaskets
When clients face extreme conditions, we typically recommend jacketed gaskets for:
- High-pressure steam applications
- Services with frequent pressure fluctuations
- Systems requiring maximum containment security
