Compression Packing

The packed gland is an exceptionally reliable fluid sealing device that is simple to install and maintain. Not only is it highly versatile, but also remarkably cost effective in both plant downtime and materials – especially when compared to complex alternatives.

Our constant advances in materials and lubricants, product design and manufacturing techniques, keep us at the forefront of compression packing technology.

We therefore bring you one of the widest ranges of packings to match the temperatures, pressures and speeds of your most modern fluid handling systems, and economical packings for your older plant.

Many of our packings will dramatically reduce your stock holding levels – as one carefully selected length-form product can often be used for many different valves, pumps and other fluid handling plant at your site.

Style #6 – All-Vee — V Ring Packing – V Rings seat automatically and are pressure-sealing. They keep equipment running smoothly and reduce maintenance. They are designed to make the pressure increase the sealing action. All-Vee Rings expand toward the rod and stuffing box wall on the power stroke or with increased pressure to automatically form the seal. On the return stroke or with pressure relaxed, All-Vee Rings contract from the rod for free movement with minimum friction.
