Abstract
An improved seal for use in fluid systems such as a water jet system includes an outer seal point that is very close to an inner seal point. By spacing these two seal points very close together, the force on the seal is greatly reduced compared to the prior art. In the disclosed embodiment, the outer seal point is on an angled forward face of the seal that abuts a back-up ring angled face. The inner seal point is between the seal and an internal shaft which rotates relative to a housing.
