Garter Springs

Stock sizes in stainless steel and hard-drawn steel

Garter springs are extension springs with the ends fastened together to form a ring.
They are primarily used to maintain controlled pressure of a radial lip seal on a shaft
and to compensate for lip wear, changes in volume or stiffness of the elastomer
caused by the fluid, and the effect of temperature changes and time. Other uses
include small motor belts and electrical connectors.

SPEC garter springs are engineered and manufactured to provide a consistent and
reliable product. They feature high initial tension to provide constant load and a
special tapered end to assure a strong connection and a continuous near uniform
body diameter.
