PTFE Packing

ML 2235 Pre-lubed Yarn Packing

  • Construction: Multi-Lok Braid
  • Features: Unlike other PTFE fluocarbon filament packing, SEPCO pre-lubricates the yarns to provide a softer, more flexible packing, with improved peripheral speed characteristics and exothermic properties.
  • Equipment: Any equipment where braided packing is commonly used.
  • Recommended For: The most severe services. All oxidizers and corrosives with one exception: molten alkali metals.
  • Limitations: Shaft speeds to 1202 FPM; pH range 0 – 14. Remarks: No glazing at higher speed applications, inert, virtually indestructible lower coefficient of friction, thermal resistance to 500°F/260°C; and high compression strength.

ML 2236 FDA: Pre-lubed PTFE Yarn Packing

  • Construction: Multi-Lok Braid
  • Features: Pure PTFE filament lubricated with a proprietary lubricant that satisfies FDA requirements.
  • Equipment: Any equipment where braided packing is commonly used.
  • Recommended For: Applications in the food processing industry or where an FDA material is required.
  • Limitations: Shaft speeds to 1202 FPM; temperatures to 500°F/260°C; pH range 0 – 14.

ML 2238 High Speed PTFE Packing

  • Construction: Multi-Lok Braid
  • Features: A new improved PTFE yarn for high speed applications.
  • Equipment: Rotating pumps and agitators with peripheral shaft speeds too fast for other PTFE packing.
  • Recommended For: All chemicals and corrosives.
  • Limitations: Addition of new lubricants reduces the inertness slightly. Shaft speeds to 1885 FPM; temperatures to 500°F/260°C; pH range 0 – 14.
  • Remarks: Use this specially treated PTFE packing where other PTFE filament glazed or hardened because of frictional heat from high speeds and thermal expansion.

ML 2254 Treated PTFE Yarn Packing

  • Construction: Multi-Lok Braid
  • Features: Style ML 2254 PTFE fibers are treated with a PTFE dispersion, which fills and seals all interstices in the packing fibers. After braiding, a PTFE coating is applied and the packing is forced air dried. This packing will not wick.
  • Equipment: Valves, expansion joints and static applications.
  • Recommended For: All severe chemical and corrosive services where an inert packing is essential.
  • Limitations: Temperatures to 500°F/260°C; pH range 0 – 14. For static applications.
  • Remarks: Excellent valve stem packing for all chemicals and corrosives; inert to all fluids except molten alkali metals.
