ABSTRACT:
A sealing connection between first and second members having coacting telescoping ends. A resilient U-shaped metal seal ring is positioned in a groove in the first member and seals against both the first and second members and includes a soft metallic seal coating. Projections extend from the seal on each side of the soft coating for protecting the coating as the members are engaged. Recesses are provided in the second member for receiving the projections and allowing the metallic seal to engage the second member. A transitional surface on the end of the second member engages the projection means for compressing the metal seal as the members are engaged.
