Graphite GFO 1/4" Gland Packing 1 Meter Quality gland packing

Description

Select Seals Style 2301 Gland Packing
Description
Style 2301 packing is a Graphite enhanced Expanded PTFE braided packing. This dense and resilient
product has the ability to withstand extreme chemical attack. The high surface speed capability of this
product, together with resistance to hardening, has proven that it can easily be used as a plant
standardization product.
Construction
Style 2301 is a braided packing constructed of Expanded Graphite filled PTFE yarns which have been
inter-braided into a dense, but flexible product that is extremely gentle on shafts. PTFE tape and
Graphite have been locked together in such a manner that the maximum benefits are gained from both
these wonderful materials. There are no added lubricants that can migrate out of this product; the
lubrication is included in the yarn.
Application
Style 2301 is ideally suited for pump applications due to its material characteristics. The ability to
remove heat from the surface contact area, while remaining flexible, makes this one of Industry’s most
widely used gland packing. Use in valves has also proven most successful due to the dense
construction of the yarn, allowing no penetration by the sealed medium. PTFE has become the
industry standard for harsh Acidic or Alkaline applications due to the ability to withstand the attack.
When Graphite is included in the material the advantages are even greater. This product is used
throughout all the different industries in almost every application imaginable, limited only by severe
temperature and very strong oxidizers such as fuming Nitric Acid, Fluorine, Aqua Regia and Oleum.
