Gland Packing Materials
At Vulcan Seals, we provide comprehensive material information to ensure you choose the right seals for your applications. Our resources empower you with the knowledge needed to make informed decisions.
Gland packing is typically constructed from braided or twisted fibers that are compressed and inserted into a gland or cavity to form a seal between two moving parts. The construction of gland packing can vary depending on the material and application requirements, but here are some common features of gland packing construction:
- Our square-braided gland packing is made from the most advanced specification braiding machines available.
- 24 and 36 track braiders are used to produce 4-ply, square inter-braided gland packing for all sizes from 3/8” (10mm) upwards.
Gland packing produced using outdated braiding machines lacks the strength of regular cross-lock construction, is less dense, and has an uneven cross-section. The looser the braiding, the lower the durability of the gland packing.
As a result, higher gland pressure is required to achieve a proper sealing effect, which increases mechanical stress. As the gland packing deteriorates, more frequent adjustments become necessary, further increasing mechanical stress and
accelerating failure.
