The V-seal can be completely assembled without the need of tools. Being all rubber, it can stretch up to 250% of its molded I.D., so it can be easily stretched over flanges, collars, and entire bearing housings during assembly. This same resilience holds the seal in place without the need for springs or clamps. To assemble the seal, it is stretched onto the shaft by hand and then pushed up against the counterface to a pre-determined width.
