STYLE 800 URETHANE U-SEALS |
![]() |
|
Style 800 U-seals are molded from tough,
abrasion-resistant polyurethane. The four lobed
expander ring energizes the sealing lips, even at
zero pressure, to help prevent 'weeping' when the
system is idle. This style can also be
supplied in various materials including: H-NBR,
X-NBR, Hytrel, Flurocarbon (VITON), NBR, and others.
