An O-ring seal is a simple, toroidal (doughnut-shaped) mechanical seal consisting of a looped elastomer or other material designed to fit into a groove or gland. When compressed between two mating parts, it creates a seal to prevent the escape of fluids or gases. O-ring seals are widely used in both static (non-moving) and dynamic (moving) applications due to their cost-effectiveness, ease of use, and ability to maintain a reliable seal under pressure.

They seal over a wide range of pressure, temperature and tolerance.
Ease of service, no smearing or retightening.
No critical torque on tightening, therefore unlikely to cause structural damage.
O-rings normally require very little room and are light in weight.
In many cases an O-ring can be reused, an advantage over non-elastic flat seals and crush-type gaskets.
The duration of life in the correct application corresponds to the normal aging period of the O-ring material.
O-ring failure is normally gradual and easily identified.
Where differing amounts of compression effect the seal function (as with flat gaskets), an O-ring is not effected because metal to metal contact is generally allowed for.
They are cost-effective.
Application
Aerospace and aviation: Aircraft engines, hydraulic systems, and other critical components
Medical devices: Medical equipment such as syringes, pumps, and valves.
Plumbing: Pipes, faucets, valves, and other plumbing components to prevent leaks.
Hydraulics and pneumatics: Create a seal between moving parts such as cylinders, actuators, and pistons.
Food and beverage processing: Processing equipment to prevent contamination and ensure hygiene.
Electronics: Electronic components such as connectors and switches to prevent moisture and dust from entering.
Common household applications: Doors, windows, and containers to prevent leaks and maintain airtight or watertight seals.
Craftsmanship
Extrusion
Raw materials for o-rings are forced through a ring-shaped die. Sometimes extrusion involves a hopper, where the material is heated. Afterwards, the material is put through the die. Different forms of extrusion include friction extrusion, cold extrusion and microextrusion.
Injection Moulding
Injection moulding is similar to extrusion in that it involves raw materials and a mould. Metal can be used, but usually it's plastic polymers in the form of pellets. Thermoplastic elastomer is commonly used for injection moulding to make o-rings and seals. The pellets are heated and the liquified material is then injected into a mould, where it cools and hardens.
Pressure Moulding
Pressure moulding is also known as compression moulding. This manufacturing process uses heat and pressure to create o-ring seals. Let's say you're making rubber o-rings. The rubber is first preheated before being injected into a mould cavity. A plug is then fitted on top, putting pressure on the mould cavity. As the pressure intensifies inside of the cavity, the preheated rubber takes its o-ring shape.
Transfer Moulding
Transfer moulding is similar to pressure moulding. Both involve preheated materials and a mould cavity. While compression moulding requires an open mould cavity, transfer moulding uses an enclosed mould cavity. As the cavity is closed, higher pressure builds. The result is thicker and more consistent o-rings.
