Premium Braided Mechanical Packing
Style 333
Patented Technology
SWEET SPOT & BEST USES:
Very High Pressure and High Temperature Valves. Specifically designed for valves with worn or suspect stem conditions.
Graphite with helically braided Inconel wire inside
Construction
Made of ultra-high purity graphite fiber with helically braided inconel wire inside. The core is extra dense to provide dimensional stability throughout the working temperature/pressure range of Style 333. Braid blockage is provided by a unique dispersion containing ultra fine graphite particles locked in place by the SealRyt® patented process.
Characteristics
- Style 333 effectively seals ALL types of valves and soot blowers, even those hard to seal.
- It is equally effective on new or old, pitted and scored equipment, without the need for bull-rings.
- It is built to require little or no adjustment through its life and to facilitate ease of removal.
- Inconel helix is completely internal, ensuring non-contact with sealing surface under normal operating conditions.
