Tooth-Type Gaskets
High-Performance Tooth-Type Gaskets for Industrial Applications
Tooth-Type Gaskets are specialized sealing solutions designed for high-pressure and high-temperature applications. These gaskets feature a unique serrated design that provides superior sealing performance compared to traditional flat gaskets.
Key Features of Tooth-Type Gaskets
- Engineered for extreme pressure conditions (up to 10,000 psi)
- Temperature resistance from -200°F to 1000°F (-129°C to 538°C)
- Available in various materials including 304/316 stainless steel
- Serrated tooth design ensures excellent load distribution
- Customizable sizes from 1/2" to 60" diameters

FAQ About Tooth-Type Gaskets
What makes Tooth-Type Gaskets different from standard spiral wound gaskets?
Tooth-Type Gaskets feature a unique serrated design that provides multiple sealing points compared to the single sealing surface of spiral wound gaskets. This design offers better stress distribution, reduces flange loading requirements, and provides more reliable sealing in high-vibration applications.
Applications of Tooth-Type Gaskets
These gaskets are widely used in:
- Oil and gas pipeline systems
- Power generation plants
- Chemical processing equipment
- Refinery applications
- High-pressure vessels
How do I determine the correct Tooth-Type Gasket for my application?
Selecting the proper Tooth-Type Gasket requires considering four main factors: 1) Operating pressure and temperature ranges, 2) Media being sealed (chemical compatibility), 3) Flange material and surface condition, and 4) Required compliance standards (ASME, API, etc.). We recommend consulting our technical team with your specific application details for optimal gasket selection.
Performance Comparison
| Feature | Tooth-Type Gasket | Standard Gasket |
|---|---|---|
| Sealing Efficiency | 95-98% | 85-90% |
| Pressure Resistance | Up to 10,000 psi | Up to 5,000 psi |
| Reusability | Limited (1-2 reuses) | Not recommended |
What maintenance is required for Tooth-Type Gaskets?
Tooth-Type Gaskets require minimal maintenance but should be inspected during routine equipment shutdowns. Check for visible damage, corrosion, or excessive compression. Always replace gaskets showing signs of permanent deformation or surface degradation. Never reuse gaskets in critical service applications unless specifically rated for reuse.
Installation Guidelines
- Ensure flange surfaces are clean and free of damage
- Verify gasket size matches flange dimensions
- Center the gasket properly before bolt tightening
- Use crisscross bolt tightening pattern
- Torque bolts to recommended specifications
