manually operated metal valves, namely, needle valves; metal seals

Snubbers, namely, pipeline devices containing pistons for gradually releasing sudden and excessive pressure into gauges and thereby reducing pulsation and vibration; and syphons, namely, coiled pipeline devices used in line between steam sources and gauges and containing water in the coils in order to isolate gauges from the damaging effects of direct contact with steam

Gauges, namely, vacuum for use in visually indicating the vacuum level of a connected vacuum system; meters, namely, digital indicators for conversion of pressure, vacuum, temperature, force, flow and other physical property measurements into electronic signals; test kits, namely, carrying cases containing testing and diagnostic equipment such as meters, transducers and transmitters for evaluation of pressure, vacuum, temperature, force, flow and other physical properties; thermometers not for medical use; thermowells, namely, containment devices to isolate thermometers from a harmful environment or excessive pressure; transmitters and transducers, namely, industrial pressure and vacuum devices that convert pressure and vacuum measurements into electronic signals; magnetic, gauge and transmitter switches; pressure and vacuum switches [ ; and solenoid valves ]
