Product Information
Vulcan Grafan material is essentially pure carbon in Graphite form processed into a flexible foil material without any fillers, binders or other additives. The product is self-lubricating, dimensionally stable, impervious to gases and fluids, and shows exceptional temperature and chemical resistance. Grafan offers unrivalled sealing capabilities under extreme temperature, media and pressure conditions giving extended packing life.

Graphite in this form is self-lubricating with a low coefficient of friction (comparable to Teflon), high thermal conductivity and permanent volumetric elasticity (spring back) which results in no volume reduction (compression set) in use. Resilient with ideal fluid and gas sealing characteristics and extreme capabilities, Grafan offers the ultimate range and performance in a packing material.

Vulcan Type VR1 is a crimped Graphan Ribbon Tape, available from 6mm to 75mm wide, for in-situ packing of pump valve stems and then it is easily compressed into a uniform packing ring. Using this system, a small tape inventory can pack any size gland with superior service results.

Applications
As per Type VR3 below, but for static use only.
