 The big advantage

The big advantage of choosing Thermabraid Braided Packing over ribbon material or molded rings is in it's ease of use. There are no precision measurements to be made, no expensive dies and no wrapping of lengthy strips of ribbon around the valve stem.

There is no inventory of different size rings for different valves, no "splitting" of rings to fit around awkward shafts and no question as to whether you are installing the right ring.

Thermabraid is convenient, easy to use, and available in square cross sections from 3/16" to 1".

Simply cut the material to a length sufficient to surround the valve stem within the stuffing box and repeat the procedure for the appropriate number of rings (see installation instructions for details).

Thermabraid Braided Packing saves time and cost installation and delivers the sealability for which flexible graphite is known. Give your  Thermabraid representative a call for  more information and test samples.
