The first aspect that users will notice about this product is the original seal design, which ensures great performance improvement of the back-up ring and o-ring commonly used in the grooves of type MIL-G-5514F. In addition to this, the double-acting sealing element is energized by an elastomer o-ring.

Next, the design also demonstrates excellent friction properties, as well as good dry running and stick-slip free starting. Note that there is a full range of sizes available, which suit all grooves of type AS4716 and MIL-G-5514F. Custom designs are also available on request.
