Sentinel Model S-22 has a circular base with full 8" opening, A.P.I. standard bolt circle and hillside flange included. All other parts are non-ferrous metal, light in weight, yet rugged in construction. The oblong 22" drain pan gives ample room for dumping the oil thief, thus insuring a clean tank deck. The spring actuated pressure and vacuum valves are combined in one unit, easily accessible for cleaning or repair. All gaskets are of neoprene, though other materials are available, and springs are plated to insure against corrosion from gases or acids. Attention is especially called to the patented bleeder latch designed for maximum safety when opening the hatch.
