KEVLAR® offers a unique combination of extremely high tensile strength, lasting resilience, low thermal expansion, low coefficient of friction, and wide chemical resistance. **Vulcan Seals Type VK4B** Kevlar® gold fibre packing is a true multi-service packing that is well suited to the needs of many industries, particularly where physical strength in packing is required. The strength of KEVLAR® is ideal for use as anti-extrusion, abrasion-resistant, backup rings, with other packing types, to increase the life of any packing combination.

Why Choose the Vulcan Seals Type VK4B?

• Impregnated with PTFE dispersion
• Suitable for Pumps (rotary and reciprocating) and valves, including high-pressure or high mechanical loading conditions
• Superior lubrication leads to less wear and higher shaft speed capability

The **Vulcan Seals Type VK4** is manufactured from KEVLAR® Aramid fibres. In order to get maximum benefit from this material, **Vulcan Seals Type VK4 **is specially treated with a high concentration of resilient, food-quality lubricants and heavy PTFE dispersion. The resulting packing significantly reduces the shaft wear problems which have sometimes been associated with other KEVLAR® packing and, with this increased lubrication, higher shaft speeds of up to 4000 fpm (20m/s) can be handled. **Vulcan Seals Type VK4**, KEVLAR® Aramid fibre lube packing, is a durable, economical general service packing for 80% of plant needs. The strength of fibre and construction of the **Vulcan Seals Type VK4** leads to long packing life with extended periods between necessary gland adjustments.

Why Choose the Vulcan Seals Type VK4?

• Treated with a high concentration of resilient, food-quality lubricants and Heavy PTFE dispersions
• Significant reduction in Shaft wear problems
• Durable and economical general service packing
• Long packing life with extended periods between necessary gland adjustments
• Suitable for rotary and reciprocating pumps, stern glands, hydraulic presses, mixers, and valves

The **Vulcan Seals Type VG1L** is an alternative packing for light duties. Equipped with inter-braided from continuous filament, textured air-blown glass fibres thoroughly impregnated with mineral oil lubricants and graphite. A dressing and corrosion inhibitor is further applied to the yarn to improve wear resistance. The **Vulcan Seals Type VG1L **will handle non-mechanically demanding plant applications whilst requiring low gland pressure to seal, reducing shaft wear and gland maintenance. **Vulcan Seals Type VG1L** for general plant service, at elevated temperatures, only if Carbon or Graphite fibres are not required. Glass fibres offer exceptional temperature resistance but are relatively low in strength. Up to 480°F (250°C), use Vulcan Seals Type VG2 for superior performance or Vulcan Seals Type VK1L where higher mechanical load or very abrasive conditions exist. At higher temperatures, Vulcan Seals Type VC5 or Vulcan Seals Type VG4 are preferred.

Why Choose the Vulcan Seals Type VG1L?

• Thoroughly impregnated with Mineral Oil lubricants and Graphite
• Suited to general-purpose packing for rotary and reciprocating pumps, mixers, and valves.
• Reduces Shaft wear and gland maintenance

The **Vulcan Seals Type VG1D **is square braided from continuous filament, texturised glass fibres reinforced with Inconel wire, and impregnated yarn by yarn with pure Graphite powder and a corrosion inhibitor. **Vulcan Seals Type VG1D** graphited glass packing is designed as a substitute for classic asbestos packing with high-temperature capability. The addition of Inconel wire reinforcement results in a true high-pressure and high-temperature traditional valve packing that has the advantage of being non-asbestos.

Why Choose the Vulcan Seals Type VG1D?

• Impregnated Yarn by Yarn with pure Graphite powder and a corrosive inhibitor
• Designed as a substitute for classic Asbestos Packing
• High-pressure and high-temperature traditional valve packing

The **Vulcan Seals Type VG8D** is inter-braided from continuous filament, textured, air-blown glass yarns.

The **Vulcan Seals Type VG8D** can replace traditional packing in general, non-arduous duties, whilst being of superior square inter-braid construction. Consider that **Vulcan Seals Type VG8D** air-blown glass fibres are kinder to the shaft and you have a naturally square packing that will seal with less gland pressure, significantly reduce shaft wear and gland adjustment and increase packing life in light duties.

Why Choose the Vulcan Seals Type VG8D?

• Thoroughly Impregnated with PTFE dispersion
• Designed as a Valve Packing
• Suitable for a variety of static or slow moving applications up to 4 m/s
• Significantly reduces shaft wear and gland adjustment

Increasing environmental awareness and legislation make consideration of the material, braid quality, and performance of tank lid packing of paramount importance. The **Vulcan Seals Type VT6** is widely used in the static and road tank industry as a quality example of braided tank packing.

Why Choose the Vulcan Seals Type VT6?

• High chemical resistance - full pH range
• Pure Poly Acrylic Nitrile (PAN) fibres
• Thoroughly impregnated with PTFE dispersion
• Specifically designed for tank man lids

The **Vulcan Seals Type VG2** is constructed using a composite yarn manufactured from high-quality PAN fibres combined with pure Carbon fibres. The in-built lubrication and superior packing fibre properties of this composite yarn are further enhanced by a thorough Graphite impregnation and high temperature lubricants. **Vulcan Seals Type VG2** is a soft, conformable packing, with a square, inter-braided, lattice construction, which creates improved sealing contact with less gland pressure. The self-lubricating PAN fibre, reinforced with Carbon and heavily coated and impregnated with Graphite lubricants, practically eliminates shaft scoring. The **Vulcan Seals Type VG2** gives extended packing life, with reduced shaft wear and gland maintenance.

Why Choose the Vulcan Seals Type VG2?

• Composite yarn: Poly Acrylic Nitrile (PAN) fibres with pure cotton fibres
• Inbuilt lubrication enhanced by graphite impregnation
