Chesterton Steel-Trap manway gaskets combine a rugged metal core with a resilient graphite (or PTFE) filler to deliver exceptional sealing performance. Engineered for high-pressure, high-temperature, and thermally active environments, these gaskets resist creep, maintain compression, and offer reliable recovery.
Designed specifically for manway and access-cover applications in petrochemical, power, and industrial plants, Steel‑Trap gaskets ensure long-lasting, leak-free performance—supporting safe maintenance and operational integrity.
