Anti-extrusion ring prevents seal extrusion in high-pressure applications by reinforcing gasket materials.
An anti-extrusion ring is a rigid or semi-rigid component installed adjacent to elastomeric or soft seal gaskets in mechanical assemblies. It functions as a physical barrier that restricts the deformation and flow of the primary sealing material under high pressure, temperature, or dynamic loading conditions. Typically positioned in the gland or groove, it maintains seal geometry, prevents extrusion into clearance gaps, and extends seal service life by reducing wear and failure modes associated with material displacement.

Its primary function is to prevent the extrusion or deformation of soft seal materials under high pressure, temperature, or dynamic conditions, thereby extending seal life and maintaining system integrity.
Select based on operating conditions: use PTFE for chemical resistance, metals like bronze for high temperatures, and engineered plastics like PEEK for combined high pressure and temperature. Consider compatibility with fluids, pressure ratings, and thermal expansion.
They are commonly used with elastomeric seals (e.g., O-rings, gaskets) in dynamic or static applications where clearance gaps exist. They are not typically needed for metal seals or in low-pressure systems.
