Kaxite Sealing is a leading China-based manufacturer and supplier of double jacket gaskets – precision‑engineered metal‑enclosed sealing solutions designed for the most demanding industrial applications. Our double jacket gaskets feature a thin metallic outer shell that fully encloses a resilient filler material (graphite, PTFE, ceramic, or non‑asbestos). This complete encapsulation protects the filler from pressure, temperature, and corrosion, ensuring long‑term sealing integrity in heat exchangers, pipeline flanges, pressure vessels, and valve bonnets.
Available in any shape and size – round, oval, rectangular, or custom profiles – with internal ribs (pass partition bars) for multi‑stream applications. As a trusted factory direct supplier in China, Kaxite offers exotic jacket alloys (SS316L, Inconel®, Monel®, Titanium), custom filler materials, and competitive wholesale pricing.
