Product DescriptionAS568 Standard Quad Ring Hydraulic Quad-Ring
Seals Rubber X RingX-rings can be used in a wide variety of static
and dynamic sealing applications. They are available in
standard O-ring sizes. Their four-lobed design provides a
larger sealing area in comparison to a standard O-ring. The
double seal action requires lower squeeze levels to maintain an
effective seal, thus reducing friction level and improving seal
life. X-ring parting lines are between the lobes, away from
the sealing surface, therefore eliminating the problems of leakage
often resulting from a parting lines irregular surface as found on
an O-ring. X-rings are designed to out perform a standard
O-ring in rotary seal applications. The four lobed
configuration creates a more stable seal avoiding spiral twisting
which can occur in reciprocating applications. What's the
difference between Quad Rings&O-Ring?Differences Between Quad
Rings & O-Rings There are several main differentiators that
separate standard O-Rings from X-Ring's four-lobed design. Standard
O-Rings are built with a basic layout that provides simple leak
protection, while Quad Rings have numerous advanced design
qualities that allow them to provide enhanced protection. Quad Ring
Seal's offer a unique spiral twist design coupled with an inner
lobe sealing surface that allows for prolonged seal life and
improved operational quality.Buna (or Nitrile) material is great
for all but the most extreme applications. It works from
-40-degrees F to 250-degrees F, and has good wear resistance. It
works with oils.FKM (or Fluorocarbon) works for almost every
application. It can withstand temperatures from -25-degrees F up to
400-degrees F. MaterialHardness (Shore
