Parker TechSeal hollow O-ring is a low closure force sealing solution
for enclosure applications and many other static applications.
O-ring has a compressive force of a lower durometer material and
physical property of a higher durometer material, reducing the stress exerted on the
TechSeal designs and manufactures hollow O-rings in standard series and friction-fit series. The friction-fit hollow O-rings can retain themselves inside the groove during component assembly and disassembly without the need for additional attachment methods.
The below videos of hollow O-rings feature the advantages and benefits of extruded and spliced hollow O-rings, as well as instructions on how to install a hollow O-ring properly.
