An excellent valve stem packing for use in high temperature and pressure steam service.
The construction features an outer jacket of wire-reinforced carbon
yarn over an improved core, allowing increased service life. The unique
construction of the outer jacket encapsulates the Inconel™ alloy
wire reinforcement in the carbon yarn. There is no wire in contact with
the stem; therefore, stem wear is virtually nonexistent.
Tested by an
independent laboratory at 1000 psi and temperatures to +1200oF line showed
that 127-AFP seals at lower torques, lasts longer between repackings,
and requires 17% - 39% less operating torque than the similar asbestos
based packings.
Certifiable to less than 200 ppm Leachable Chlorides
