Beschreibung
Zusammenfassung:	A downhole tool including an insertion member arranged to insert into and form an annular seal with a receiving member using an annular seal assembly. The seal assembly 5 includes a compliant metal spring and a separate metal cover overlapping at least a portion of an outside of the spring, wherein the cover and spring extend radially outward from the downhole tool so as to be compressed when the insertion member is inserted within the receiving member to form an annular metal-to-metal seal between the insertion member and the receiving member. A method of coupling the downhole tool and the receiving member 10 in a well includes inserting the insertion member of the downhole tool into the receiving member and energizing and forming an annular metal-to-metal seal by compressing the seal assembly between the insertion member and the receiving member when inserting the insertion member into the receiving member. 15
