Series 700 (Series 500) Flat Glass Gagecocks

Offset Pattern Design Series 700 OS&Y (Straight Pattern Design Series 500 OS&Y) are outside screw and yoke design used for high temperature and corrosive liquids applications. The OS&Y design isolates the stem threads from the liquid. The Gaugecocks provide a 90° connection to the process vessel and isolating the gauge chamber from the liquid content of the vessel. Gagecock leakage is Class 1 per ISA RP39.6. These units are used in conjunction with direct reading flat glass gauges in the petroleum, chemical and general process industries.
