Bal-Seal’s sealing products line has added the spring-energized polytetrafluoroethylene (PTFE) C-ring seal, which can be retrofit into grooves designed for elastomeric O-rings. This offers improved performance and service life in hardware with large tolerance variations. The C-ring seal combines the low-friction properties of PTFE and simple, streamlined jacket geometry to improve sealing for more cycles in equipment where clearances, surface finishes, and other design characteristics vary widely. The C-ring seal is energized with a Bal Spring canted coil spring, which promotes even wear and prolongs service life. Its design allows for tool-less installation.
Typical applications include medical imaging units, insulin pumps, ventilators, and drug-delivery devices.
