PTFE Packing

Pre-lubed Yarn Packing

  • Construction: Multi-Lok Braid
  • Features: Unlike other PTFE fluorocarbon 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.

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.

Treated PTFE Yarn Packing

  • Construction: Multi-Lok Braid
  • Features: 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.
