Zusammenfassung:	A method of sealing a connection (4500) between two tubulars (4505, 4510) involves engaging a threaded end of the first tubular (4505) with the threaded end of the second tubular (4510). An annular groove (4520) is present between the tubulars (4505, 4510) and a seal (4525) disposed in the groove (4520), the seal (4525) being compressed when the tubulars (4505, 4510) are radially expanded.
