Overview
The SEPCO soot blower packing is a premium sealing assembly designed for high-temperature, high-pressure industrial applications. This 1-7/8″ graphite unit incorporates stainless steel SS452 and SS557 end rings, making it ideal for soot blower lance and steam supply pipe sealing in power plants, boilers, and heat exchanger systems.
Key Features
- Graphite packing rings with proprietary carbon/graphite blend for thermal stability
- SS452 and SS557 stainless steel end rings for corrosion resistance
- Rated for continuous operation up to 1,250°F in steam service
- Special blocking agent prevents particle shedding and extends pack life
- Compatible with rotary and axial movement in stuffing box assemblies
- Drop-in replacement for standard SEPCO soot blower seal configurations
