SPNS type hydraulic seal is a relatively soft, non-metallic ring that is captured in a groove or fixed in a combination of rings to form a seal assembly to prevent or separate fluids in reciprocating applications. Hydraulic sealing is essential in machinery. Their use is critical to providing a way to convert fluid dynamics into linear motion. Hydraulic seals can be customized to your requirements.

SPNS is single-acting O-ring energized rod seals have proven to be ideal for a variety of applications. These seals are typically made from our high-quality materials and are designed with an elastomer booster to optimize performance. It can be used as a single rod seal or as a secondary seal in a rod seal system to provide optimum sealing performance.
