O-rings
Seal Dynamics offers the seal industry one of the largest available inventories of
metric O-rings, including standard O-ring sizes and non-standard (custom) sizes, as well as a large assortment of compounds. Within the seal industry, there are several widely known O-rings that comprise the bulk of those used across most industries and applications. These are known as "Common Industry Standard O-rings."
O-ring Industry Applications
Seal Dynamics' inventory is so large that we can satisfy many different industry applications that require both standard as well as custom-developed seal applications. Quad rings are a good example.
O-ring Types
Although there are many uses for O-rings, metal O-rings and metric O-rings, sealing applications involving O-rings can typically be classified as either static seals, dynamic seals, or other seal application types.
- Static Seals
- Static Axial Seals
- Static Radial Seals
- Dynamic Seals
- Reciprocating Seals
- Oscillating Seals
- Rotary Seals
- Piston Rings
- Other Dynamic Seals
