Couplings

Help join systems or mechanisms together by preventing leakage, containing pressure, or excluding contamination.

It is designed for lower operating pressures than hydraulic seal. Pneumatic applications also typically demand higher operating speeds and lower friction seal than hydraulic applications. These seal may be used for rotary and reciprocating motion.
 

It is a relatively soft, non-metallic ring, captured in a groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocation motion applications.

OIL SEAL a device using oil as the sealing medium to prevent the passage of fluid from one chamber to another.

Contain pressure on both sides of a piston, which is applied from either direction. 

It is designed to seal the rotating assembly in the stationary compressor case.

It is stack of multiple sealing rings (middle rings), support ring (top adapter), and a pressure energizing ring (bottom adapter), are popular for sealing rods and pistons in medium to heavy duty applications and are compatible with both single and double acting cylinders.
