Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges. A manometer is a good example, as it uses the surface area and weight of a column of liquid to both measure and indicates pressure.

( Customer review)
A mechanical seal or “O” ring is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets.A stationary seal may also be referred to as 'packing'.

MS GI Plated Hydraulic Fittings
( Customer review)
Hydraulic fittings connect conductors such as hoses, pipes and tubes in a hydraulic system. Most fittings have a male and female component that joins to form a connection. These connections help contain and direct the flow of hydraulic fluid in the conductor while preventing leaks and maintaining pressure. Different fittings allow designers to change flow direction, the elevation of lines or split flow. Crimping is the most common method for assembling hoses and fittings. Once the crimp specifications have been checked for the specific hose and fitting, a crimping machine is adjusted to the appropriate crimping diameter setting. The next step is to lubricate the fitting, put it on the end of the hose, and then put it in the crimping machine.
