606

The Hallite 606 single-acting, single lip asymmetric piston seal is designed with precision trimmed sealing lips to provide effective bore sealing in light and medium-duty applications. The seal can be considered for use in heavy-duty applications when used with a suitable full depth back-up ring. The sealing lips are trimmed at an angle to give optimal rod sealing performance.

The range covers most standard housings used in Europe, North America and Asia.

The Hallite 606 is designed to have an interference in the seal housing groove. The outer dynamic lip is shorter and more robust to improve sealing and compression set characteristics over conventional, symmetrical U-rings.

The seal is recommended for use in single-acting piston seal applications. It can also be fitted back-to-back in separate grooves for use in double-acting applications.

The Hallite 606 is moulded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance.
