It fit a ⅝” pipe, and was made by the National Meter Company in Brooklyn, N. Y. The Magnoseal, introduced in 1912, was apparently a magnetic drive designed to eliminate the stuffing box, a device that prevents leakage along a moving part passing through a hole in a vessel containing steam, water or oil.
