The R23 is a double-acting, o-ring energized, low-friction rod seal that performs well in both high-and-low pressure systems. High-performance materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility. The standard R23 seal face includes pressure notches, which makes the seal very responsive to changes in pressure or direction of travel.

This design also fits standard ISO 7425-2 grooves and is offered in a wide range of metric and inch options. With proper guidance (see Bearings section), the R23 is an excellent long-lasting sealing solution.
