Gaskets

Industry Definition & Scope
The gaskets industry encompasses the design, manufacturing, and supply of sealing components placed between mating surfaces in mechanical assemblies to prevent leakage of fluids or gases. As critical sealing solutions, gaskets ensure system integrity, safety, and efficiency across industrial, automotive, aerospace, and infrastructure applications by creating reliable static seals under compression.
