Sealing a pump casing around the shaft periphery to prevent the pumped liquid from leaking into atmosphere is a major concern. Effective sealing can be accomplished by providing the pump with mechanical seal or packing rings. That part of the pump casing that contains the mechanical seal or packing rings is called the stuffing box.

The failure of an o-ring or seal can cost the customer  time and  money as well as possibly endangering personnel.

Hydraulic cylinder seals are located inside of the cylinder barrel. Seals may be installed on the end cap at the base of the cylinder or at the rod end, but all cylinders will have one or more very important seals installed on the piston.

Pneumatic Seals are the ones used in pneumatic cylinders and valves. A pneumatic cylinder or valve is one that is air or gas-actuated, at the desired pressure levels. An air-powered or driven device needs to make use of high quality seals so as to maintain the specified pressure level and to safeguard against leaks and ruptures.
