Product Description
VR4.7/16 7/16inch Grafan & Graphite Fibre Gland Packing x 8m

Vulcan Type VR4 combines and maximises the performance of Expanded Graphite and Graphite fibres. Expanded Graphite is the ultimate valve sealing material, but it may extrude or deteriorate, in more mechanically demanding, rotary applications. The addition of Pan Graphite fibres adds strength and increases heat dissipation, which further enhances the packing¡¯s life and performance.

VR4 is square inter-braided, with the Pan Graphite fibres running from core to the corner posts, to give dimensional stability and to resist extrusion. The Expanded Graphite fibres are braided to the packing surfaces, to enhance smooth running and sealing performance. Vulcan VR4 is THE Expanded Graphite packing for use in rotary applications. Shaft wear and gland maintenance are virtually eliminated, as the packing is self-lubricating and includes, passive, corrosion inhibitors. VR4 standard spool length is 8 metres.

Applications: Maximum capability, rotary Gland Packing, for an extreme range of duties, against virtually all chemicals and temperature conditions.
