Sight Level Gagecocks, Offset Pattern – Series 300, 400

Series 300 and 400 feature the offset pattern design and provide 90° connection to the process vessel and isolate the gage chamber from the liquid content of the vessel. Gagecock leakage is Class 1 per ISA RP39.6. These gagecocks have internal screw threads that are wetted by the process liquid. They are used in conjunction with direct reading flat glass gages in the petroleum, chemical and general process industries. Offset gagecocks permit the inside of the gage glass to be cleaned with minimum disassembly by removing vent and drain plugs (or other connection) and inserting brush through the vent or drain.
