The worlds simplest and most widely used sealing solution

The R-type O-ring is a circular ring with a round cross-section. This is currently the most simple and most frequently sold sealing system. It combines:

maximum efficiency,
small size,
low cost,
symmetry avoiding the risk or assembly errors.

With a wide range of uses, the O-ring can be used:

in static or dynamic assemblies,
for applications from cryogenics to very high temperatures (usually -50°C to +250°C),
with pressures from high vacuum to 2,000 bar.

It can be mounted in grooves of simple geometry that are easily machined. It will fit the smallest sizes according to its shape.
