Quad-rings® are often referred to
as X-rings, Nu-Lips®. Occasionally
they are identified by a ‘4 - (dash)’
reference. They can be used in a
wide variety of static and
dynamic sealing applications.
The four-lobed design provides twice
the sealing surface in comparison to
a standard O-ring. The double-seal
action requires less squeeze to
maintain an effective seal. This
reduction in squeeze means less
friction and improved seal life.
Quad-ring® parting lines are between
the lobes, away from the sealing
surface, thus eliminating the
problems of leakage often resulting
from a parting line’s irregular surface
as found on an O-ring.
Quad-rings® are designed to
outperform a standard O-ring in
rotary seal applications.
