Product Overview

The 353B1135P002 Seal Pin is a precision-engineered sealing component used in GE heavy-duty gas turbines. Industry spare parts references identify 353B1135P002 as a Stage 1 Turbine Seal Pin, installed within the turbine hot gas path sealing system.

Seal pins are critical components that help secure and position sealing elements between turbine stages. They contribute to maintaining proper clearance control, minimizing gas leakage, and improving overall turbine efficiency.

Operating in the turbine hot section, the seal pin must withstand:

  • High temperatures
  • Thermal expansion cycles
  • High-speed vibration
  • Oxidation
  • Centrifugal forces
  • Continuous operational stress

At Dawopu, we manufacture OEM-quality turbine seal pins using high-temperature alloys and precision CNC machining technology for power generation, oil & gas, and industrial turbine applications.
