1)
Low breakaway and running friction
allow for high running speeds.
2)
Uniseal does not allow pressure trapping
between seals.
3)
A one piece seal allows the use of a
wider wear band located at the furthest
distance from the rod bushing, providing
maximum rod support and bushing life.
4)
Seal rolling due to pressure spikes is
virtually impossible.
5)
Uniseal is compatible with a wide variety
of surface finishes and hydraulic fluids.
6)
Uniseal provides a longer service life
due to a very high resistance to wear.
1)
The asymmetrical seal design maintains a
very dry, consistent performance while
resisting rolling during pressure spikes.
2)
Superior flexibility allows for very easy seal
installation.
3)
Urethane seals are capable of running at
higher piston speeds, while wearing at a much
slower rate in comparison to Poly Pak seals
due to reduced breakaway and running friction.
