Tanged Graphite Full Face Gasket — PN40
When a seal fails in a high pressure industrial environment, the consequences go far beyond a simple leak. The Tanged Graphite Full Face PN40 Gasket is engineered for exactly these critical applications, delivering reliable, long-term sealing performance across the most demanding operating conditions.

At its core, this gasket combines expanded flexible graphite with a perforated stainless steel insert. The metal core's precision formed tangs grip the graphite mechanically, eliminating the need for adhesives and ensuring structural integrity even under intense thermal cycling and pressure spikes up to 40 bar (580 psi). The result is a gasket that holds firm where others degrade.

The full-face design extends across the entire flange face, right to the outer edge, providing uniform compression and complete bolt-hole coverage. This makes it fully compatible with standard PN40-rated flanges and particularly well suited for applications where flange rigidity may vary.

Summary: 

• Pressure Rating: PN40 - rated up to 40 bar (approx. 580 psi)
• Temperature Resistance: Performs reliably across extreme high-temperature environments, including steam lines in power plants and manufacturing facilities
• Chemical Compatibility: Resistant to harsh acids, solvents, hydrocarbons, and aggressive process fluids without degrading
• Construction: Expanded flexible graphite bonded mechanically to a perforated stainless steel core — no adhesives required
• Design: Full-face configuration with bolt-hole accommodation for flush flange coverage

Applications: 
Common applications include;

• Industrial systems
• Chemical & petrochemical plants
• Piping and machinery flanges
