SEPCO 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 500F/260C; 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 500F/260C; 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 500F/260C; 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 500F/260C; 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.  ML 2254OX Treated PTFE Yarn Packing Construction: Multi-Lok Braid Features: PTFE fibers with PTFE suspensiod. Contains no organic lubricant and is approved for oxygen service. Recommended For: All services where organic lubricants cannot be used. Limitations: Temperatures to 550F/260C; pH range 0 - 14.
