RU7
The RU7 is a single-acting dual lip Polyurethane rod seal designed to fit standard rod gland housings. The seal is molded from high-grade Polyurethane material that can withstand the harsh conditions of mining and mobile hydraulic cylinder applications. The RU7 is an excellent option to replace single or double lip non-energized u-cups and as well loaded single-lip u-cups (Type B PolyPak).
The RU7 is recommended in low to medium duty hydraulic cylinder applications but it can also be an excellent option as a secondary seal behind a buffer seal for high pressure, low temperature applications.
