Piston cup seals are made of different materials and will perform under different temperature and pressure ranges. So knowing what you need ahead of time from these types of seals is important, like temperature, pressure, air and/or fluid so that it will do its job. The main objective of a piston seal is for a piston head, plunger or ram in hydraulic or pneumatic capacity. The mechanical sealing surface can be of any kind. It is very pleasing on the cost effectiveness of this type of seal. These types of seals are used in industrial equipment, hydraulic valve and pneumatic...

Single acting cylinders need a mechanical medium in order to retract or extend the rod. In the diagram it shows it using an internal spring to project the rod out and air pressure to bring it back in. Also, if the arrangement of the spring and air pressure port, it could do this process in reverse. The seal in this diagram is a lip seal. The piston cup seal supports a very flexible seal so that it can handle large clearance while at a low pressure. This seal is very good at trapping in the injected lubricants while being placed...

This side plug in was made to work with a solenoid and a hydraulic control valve D1VW. This plug in is made so that it has four solenoid circuit posts and has two lengthy ground post to help give a rapid connect or disconnect mating for electrical connections. The extra long post give a mate first break last application that lessons the likely hood of an accidental shock. The plugin connector stream lines any speeds maintenance by getting rid of the need for creating any new electrical wire connections while taking off and/or substituting the valve. You can have another...
