The spherical containment reservoir has first and second circumferentially spaced tubular necks. A tubular bridge interconnects the first and second necks at points spaced from the reservoir. The first neck is sealed between the connecting point and the reservoir. A valve seat is situated in the second neck between the connecting point and the reservoir. The internal surface of the second neck is threaded to accept a valve stem above the valve seat.
