Characteristics and performance
Hallite’s 616 is a compact, asymmetric twin lip rod seal offering excellent dry rod sealing for light and medium-duty applications where space and friction are at a premium. The seal is manufactured in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance.
Hallite recommends using our 616 rod seal as either a single seal or in combination with the Hallite R16 PTFE rod seal. The combination is recommended for use in applications where pressure peaks may occur, such as cylinders with cushioning.
The Hallite R16 PTFE rod seal is fitted into the groove on the pressure side of the gland and the Hallite 616 is used as the secondary seal to ensure minimal leakage. Consult your local Hallite office when considering this arrangement.
