PTFE-filler 304 Inner Ring Sealing Gasket
This gasket is a specialized sealing component designed for high-performance applications. It features a 304 stainless steel inner ring, which provides structural support and enhances the gasket's durability. The spiral wound construction combines a metallic strip (also typically 304 stainless steel) with a non-metallic filler material, in this case, PTFE
304 Inner Ring Spiral Wound Gasket with PTFE Filler: Detailed Overview
The 304 inner ring spiral wound gasket with PTFE filler is a premium sealing solution engineered for challenging industrial environments. It features a 304 stainless steel inner ring wrapped with a spiral-wound combination of stainless steel and PTFE (Polytetrafluoroethylene), offering exceptional corrosion resistance, chemical inertness, and thermal stability. The inner ring reinforces the gasket’s structure, preventing deformation and blowout under high pressures (up to 2500 psi) and temperatures (up to 550°F/288°C in PTFE-compatible applications).
The PTFE filler ensures a tight, leak-proof seal by conforming to flange imperfections and resisting aggressive media. Its low friction coefficient reduces torque requirements during installation. Ideal for applications in chemical processing, food and beverage, and pharmaceutical industries, this gasket combines durability with versatility. Its ability to withstand thermal cycling, vibration, and harsh chemicals makes it a reliable choice for critical piping and equipment sealing needs.
