Hallite® Typ 513

The Hallite 513 is a standard profile loaded U-cup with precision trimmed sealing lips manufactured in either a polyurethane or polyester shell energised by a high quality O-ring and designed for common North American grooves. The sealing lips  are trimmed at an angle to give optimal rod sealing performance. In most cases, the deep profile of the Hallite 513 provides extra stability needed to resist rolling in the  groove. Together these features result in improved life and sealing. At zero or low pressure, the O-ring helps to increase the sealing force preventing  any bypass. Under most conditions as the pressure rises, the sealing force increases  and the O-ring ensures complete lip actuation. The symmetry of the Hallite 513 makes it ideally suited for single-acting rod and piston applications. However, the Hallite 513 is not recommended for use in back-toback double-acting applications.
