A seal is a ring captured in a groove to control fluid leakage

The O-Ring's design lends itself to a multitude of sealing uses including static and dynamic applications at low speed and low pressure, rotary and oscillating applications.

Seals, rubber-to-metal bonded parts, piston cups, or any other custom molded rubber configuration you design, RT/Dygert can assist you in moving your drawing from concept to production.
