Premium Braided Mechanical Packing

Style 821

Premium Quality
SWEET SPOT & BEST USES:
High Temperature chemical processes. Solvents, monomers and other non-Oxidizing chemicals

Directed towards higher temperature chemical applications which require essential chemical inertness

Construction
Multiple textiles pretwisted for desired function surrounding a pretwisted, prebraided core for density, 821 relies heavily on the attributes of very high purity carbon, polymer infused PTFE/carbon, and graphite exfoliant, with the matrix of manufacture very similar to that utilized with the versatile and durable SealRyt style 7413. All the very best characteristics of each textile combine to allow the whole product to perform where standard products cannot.
Characteristics
  • ‍Style 821 is directed towards higher temperature chemical applications which require essential chemical inertness, but also those which require far greater than normal sectional density still allowing the surface to conform
Applications
Chemical mixers, blenders, and choppers including both dry and wet are the ultimate home for this durable product. Works dependably with acids, bases and solvents.
Base Materials
  • ‍Carbon
  • Fluoropolymer
GENERAL APPLICATIONS
  • ‍Rotary & Reciprocating
  • Valve & Reciprocating
