VT9L
VT9L
Vulcan Seals Type VT9L Gland Packing is braided from pure PTFE fibres, in the form of multifilament yarns, vacuum impregnated with PTFE dispersion and saturated with chemically resistant lubricants. The PTFE fibres are pre-shrunk and square inter-braided to produce a dimensionally stable packing.
Type VT9L chemical pump packing exhibits high mechanical strength and high operational stability under demanding operation conditions, in addition to excellent non-friction characteristics. Shaft wear is virtually eliminated and Vulcan Seals Type VT9L is capable of performing in service conditions far beyond conventional packing.
Type VT9L standard spool length is 8 metres. Custom lengths can be available - please contact us using the form.
