PTFE Gasket Types and its Properties
Explore our diverse range of PTFE gaskets, each meticulously crafted to meet the unique demands of various industries. We understand that one size doesn’t fit all, which is why we offer a variety of PTFE gasket types, each designed for specific applications. Discover the perfect match for your needs.
Raised-Face Gaskets:
- Designed for use with raised-face flanges.
- The gasket’s outer diameter matches the flange’s raised face.
- Commonly used in high-pressure applications.
Full-Face Gaskets:
- Designed for use with flat-face flanges.
- The gasket covers the entire flange face, including bolt holes.
- Provides maximum sealing surface and distributes pressure evenly.
- Often used on weaker flanges.
Customized Gasket Types:
- Manufactured to specific dimensions and shapes to meet unique application requirements.
- Ideal for non-standard flanges or specialized equipment.
- Can be made from any type of PTFE.
Envelope Gaskets:
- Consists of a PTFE outer layer (envelope) surrounding a core material (e.g., rubber, fiber).
- PTFE envelope gaskets comprise a compressed synthetic fiber gasket material insert with a PTFE envelope
- The envelope protects the gasket from chemical attacks and provides required strength and resilience for demanding sealing operations
- PTFE envelope gaskets offer excellent chemical resistance under moderate conditions of temperature and pressure.
Expanded PTFE Gaskets (ePTFE):
- Made from expanded PTFE, which has a fibrous microstructure.
- Highly compressible and conformable, providing excellent sealing on irregular surfaces.
- Expanded PTFE materials have excellent creep resistance and bolt torque retention properties
- Offers superior chemical resistance and a wide temperature range.
- Often sold as tape, or sheet stock.
- Since the material is available in roll form, it offers a solution to jointing needs without the need to maintain large stocks of cut gaskets
Filled PTFE Gaskets (Glass-filled, Carbon-filled):
- PTFE blended with fillers like glass or carbon to enhance specific properties.
- Glass-filled PTFE: Increases compressive strength and reduces creep.
- Carbon-filled PTFE: Improves wear resistance and electrical conductivity.
- The fillers alter the mechanical properties of the pure PTFE.
CNAF Gasket Types and its Properties
Our product line features a wide array of CNAF gaskets, each designed to meet the specific requirements of different industrial applications. We offer various CNAF types, formulated with different fiber and binder combinations, to ensure optimal performance in diverse operating conditions. Explore our selection to find the right CNAF gasket for your needs.

- Available in sheet form and as cut gaskets
- 3xA anti-stick finish on both sides
- lower resistance to oils and fuels compared to NBR
- perform well in applications involving water, air, and other non-aggressive fluids.
- Remarkable chemical resistance
Reinforced Graphite Gaskets
The “reinforced” aspect refers to the addition of a reinforcing material, typically a metal, to enhance the gasket’s structural integrity. They’re made from pure carbon that’s been specially treated to expand its structure. This expanded carbon is then rolled into thin, flexible foils. These foils are layered together to create thicker sheets for gaskets and seals.
- Reinforced graphite gaskets are a crucial component in many industrial applications, particularly those involving extreme temperatures and pressures.
- Ideal for steam applications as they don’t harden over time.
- Long service life.
- Versatile chemical compatibility.
- Reinforced Graphite Gaskets Reinforcement:
- Tanged Stainless steel 316
- Tanged Stainless steel 304
Expanded PTFE Properties
- Combination rings or transition rings combine two different sizes having the same pitch diameter permitting bolt up of differing size flanges
