High Chemical & Extreme Thermal Gland Packing
Product Overview
SEALMAN STYLE SRS976 is a highly chemical-resistant packing with anti-frictional and non-sticky properties. Designed specifically for demanding pumps, valves, and agitators handling aggressive acids, caustics, and organic chemicals.
SEALMAN STYLE 982C is a non-asbestos expanded pure graphite yarn braided packing reinforced with Inconel wire, treated with a proprietary MoS2 based "SEALTHERM" dispersion to seal leak paths. It withstands extreme mechanical stress and cyclic temperature loads in blast furnaces and power plant steam lines.
Key Features & Engineering Benefits
- ✓ 99.85% Carbon Purity: Ultra-pure graphite yarn minimizes shaft wear and thermal oxidation.
- ✓ Inconel & SS Wire Reinforcement: Boosts structural integrity to withstand pressures up to 200 Bar.
- ✓ Passive Corrosion Inhibitors: Prevents pitting corrosion on valve stems during idle plant turnarounds.
- ✓ Universal Media Compatibility: Suitable for superheated steam, acids, caustics, hydrocarbons, and paper pulp.
