American National Standard Pipe Thread standards, often called National Pipe Thread ("NPT") standards for short, are U.S. national technical standards for screw threads used on threaded pipes and pipe fittings. They include both tapered and straight thread series for various purposes including rigidity, pressure-tight sealing, or both. The various types are each named with a symbol and a full name; examples of the symbols include NPT, NPS, NPTF, NPSC, and others.

There are many types of probes used in restaurant equipment for the measurement of temperature, humidity, liquid level, ice level, product or ingredient levels and other critical operating limits and control points (HACCP). A probe is a small device, especially an electrode, used for measuring, testing, or sensing and obtaining information. Probes are commonly thin and oblong, and may be flexible. They provide data output to other components to control operation of the equipment. 

A tube (tubular section, tubing, or hollow cylinder) usually but not necessarily of circular cross-section, used mainly to convey substances which can flow liquids and gases (fluids), slurries, powders and masses of small solids. Plastic tubing is widely used for its light weight, chemical resistant, non-corrosive properties, and ease of making connections. A tube may also reference a florescent light bulb or a housing of lamps or LEDs.
