Gland Packing

PTFE Graphite Packing

Type VT8

PTFE Graphite Packing

Vulcan Type VT8 is supplied as a double construction of a 100% unsintered PTFE core with a spiral covering of PTFE tape. VT8 provides the versatility of an extruded malleable core with the additional strength and extrusion resistance of the PTFE tape covering. The result is a low friction, extrusion resistant, TEFLON® packing with near universal chemical resistance.

VT8 will not harden nor shrink in application and provides an instant packing and instant gasket on one very economical spool. In valves, wrap VT8 round the stem to fill the gland (no need for cut rings), tighten the gland follower and the PTFE moulds to form a tight leak free seal. A
properly installed VT8 is guaranteed to last the life of the valve to which it is fitted.

Type VT8 standard spool length is 8 metres. Custom lengths can be available - please contact us using the form.

Applications: Universal PTFE sealing material for gasketing and long-life valve packing.For practically all chemicals. Not suitable for liquid or gaseous oxygen.
