Prime Features
- High thermal conductivity for cool running.
- Very good start-up and emergency running characteristics.
- Less gland adjustment, easy break-in, & even compression
- PREVENT Galvanic corrosion of the spindle/shaft
- Excellent low co-efficient of friction and minimal Shaft wear.
- Very Resilient and resistance to thermal shock & high thermal conductivity
- Significant serviceability of packing.
- Non-abrasive; hence rules out shaft scoring
- Provides better sealing in rough, wear and tear conditions.
- Special grade Sigma 171C for Nuclear Application
