Segmentation by type dissects the market into five principal gasket constructions, each with sub‑variants that tailor performance to niche conditions. Spiral wound gaskets, often offered in standard and high‑temperature grades, dominate high‑pressure pipelines due to their compressibility and leak‑tightness. Corrugated gaskets, available in reinforced and non‑reinforced forms, are favored in flange assemblies where flexibility and vibration damping are critical. Flat gaskets, including laminated and solid‑core versions, serve low‑pressure sealing in pump housings and valve seats. Metal‑reinforced gaskets, with stainless‑steel or nickel alloys, address extreme temperature differentials in heat exchangers and reactors. Composite gaskets, comprising PTFE, graphite, or aramid fibers, target chemically aggressive environments where conventional elastomers fail. The relative share of each type aligns with the application profile: spiral wound and metal‑reinforced dominate oil & gas, while composite and corrugated are prevalent in chemical and pharmaceutical sectors, collectively shaping the market’s structural composition.
