Endurance Packing System™
Engineered to Outlast Expectations.
Endurance Packing was built with one goal in mind: exceed the limits of conventional packing. This patented, industry-first innovation features an advanced header ring and newly developed chevron ring made from Vulcan’s proprietary PTFE material. Each component works together with the Vulcan plunger as a single system to deliver unmatched durability, reliability, and greater service life in even the most extreme conditions.

A Giant Leap For Packing
New Chevron Ring
Crafted from our proprietary low-friction PTFE material, the new chevron ring design increases structural rigidity for optimal load distribution, resulting in smoother operation, reduced wear, and significantly extended packing life.
Next Gen Header Ring
Introducing the first of its kind composite header ring comprised of TPU and PTFE. This optimal combination of materials provides best in class rigidity and heat mitigation.
Pressure Rings
Tried and true, industry standard aramid reinforced pressure rings.


Less Maintenance, Longer Life
New Proprietary PTFE Material
Our proprietary PTFE material provides components with a dry-film material transfer to the plunger surface, improving system life by greatly reducing friction and heat.
Fewer Risks, Safer Work Site
Longer product lifecycles mean less overall maintenance. And fewer maintenance touches equals a safer work site for everyone involved.
Designed as a System
Vulcan Plunger
The Vulcan Plunger features a tungsten carbide coating to make it more durable and resistant. Flaking is minimized via an automated coating process to ensure even distribution and strong adhesion to the base material.
Better Together
The Endurance Packing System includes the Vulcan Plunger, which is engineered to work optimally with Endurance Packing. Working together as a unit, the system reduces friction between the plunger and seal, which decreases heat and extends the life.
