Flexitallic Enviroflex™ HOT stem set is supplied as a six or seven ring set. Each set is comprised of three central die-formed graphite rings using 99.85% purity exfoliated graphite, one braided graphite over-knitted with Inconel wire inner header ring, one inner footer Thermiculite™ TR160 ring and two braided Thermiculite™ TH894 (header and footer) end rings.
The TR160 inner footer ring is optional (space dependent) and the Thermiculite™ TH894 braided rings provide a thermal oxidation barrier to protect the graphite rings at high temperatures. These materials are inherently Fire Safe.
This is a static seal only.
Available in solid ring form only (braided graphite and Thermiculite™ rings have a single split).
