Description
This Cylinder Rod Seal SPNS 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. Its use is critical to providing a way to convert fluid dynamics into linear motion. Hydraulic seals can be customized to your requirements.
The Cylinder Rod Seal SPNS is a single-acting O-ring energized rod seal that has proven to be ideal for a variety of applications. This kind of seal is typically made from our high-quality materials and is 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.
