Abstract
A lathe cut sealing ring includes a substantially cylindrical ring of elastomeric material formed about a central axis. The ring includes a rectangular cross-section and has an inner diameter, an outer diameter, opposite planar upper and lower surfaces, and a plurality of angularly spaced positioning ribs protruding inwardly from the inner diameter. This sealing ring and the groove in which it is located can advantageously be formed with simple and cost-effective lathe cutting operations.
