API 622 Fugitive Emissions Tested. Style 396 with a resilient core of Style 333 for Valve applications that need to deflect and withstand line surges. High Pressure applications.
Style 333 core, with helical braided Inconel wire, overbraided with carbon-inserted exfoliated graphite foil
A patented core of Style 333, an internally-sprung high temperature, high pressure graphite packing, over braided with carbon filament inserted exfoliated graphite foil. Style 396C is the most effectively designed product on the market today for the sealing of fugitive fuel emissions. Style 396C meets or exceeds all requirements of A.P.I. 589 and 607 tests as well as the A.P.I. fire test for soft-seated quarter-turn valves.
- Style 396C is unlike other exfoliated graphite products which offer various other yarn or wire placements to theoretically address extrusion, blow-out prevention, etc.
- Style 396C utilizes its patented Style 333 core, capable of withstanding 5800 PSI alone, to provide a highly-sprung internal structure which enables 396C to conform and re-conform through constant thermal cycling to various stem, bore and clearance conditions in various states of degradation.
