Rail infrastructure is an important national asset, heavy materials handling using Rail transportation methods are energy efficient and the safest way to move high volume materials across long haul distances.
Automotive Seals - Type H by Seal Innovations
Special design of reversed metal OD direction, suitable for special installation
Allows installation from both sides
Temperature range is dependent on the material
Seal Innovations HBY
is a two piece single acting buffer seal which consists of one special designed
elastomeric sealing element for to evacuate the back pressure and one
thermoplastic back-up ring.
• No pressure build up between the primary and secondary seal
• High wear resistance
• Low friction
• Low axial housing heights
• Good protection to the secondary seal with pressure peaks

The above data are maximum values and cannot be used at the same time.
It is recommended to have 50% to 90% of the working surface material contact
Easily assembled into closed grooves. It is very important that the assembly
tools must be of soft material and have no sharp edges. Before installation
the sealing element must be oiled with system oil.
This HBY buffer seal is always used in a sealing system in combination with
the U-Seal as they are not designed as being the main sealing element. HBY
reduces the pressure peaks on itself in order to save the main sealing
element with pressure fluctuations.
The largest sealing gap value occurring on the non-pressurized side of the
seal does have a vital importance for the function of the seal and in this
respect it is quite important to use the S value lower than the above
