Characteristics and performance
The Hallite 673 is an asymmetric, single lip U-ring rod seal designed to provide a dry sealing solution 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 seal profile has been developed to minimise friction and improve back pumping capability when used with a double-lipped wiper such as Hallite 839N, 844, and 864.
The standard material for the the Hallite 673 is Hythane® 591 which we recommend for heavier duty and earth-moving applications. As alternative, the seal is available in Hythane® 181 for easy installation and excellent low temperature performance.
