Our company seals are used for prevent oill leakage in hydraulic
systems.They need to withstand high pressure temperatures and
reduce fiction and wear to maintain high sealing performance.The
lbh type is a dust-proof ring that also prevent hydraulic oil
leakage and is suitable for low oil pressure cylinders.

Material-NBR
Nitrile rubber (NBR) is the general term for
acrylonitrile-butadiene copolymer. The ACN content can vary between
18% and 50%While the acrylonitrile content is important, the
resistance to oil and fuel is more so. Conversely,the elasticity
and compression setare not as good. The NBR has good mechanical
properties and good wear resistance. However,its resistance to
atmospheric agentsand the ozone is relatively low.

Material-FKM
Depending on their structure and fluorine content, the chemical
resistance and resistance to the cold in fluororubbers can vary.
This FKi-based rubber is very often used for high-temperature
hydraulics and pneumatics,for industrial valves,iniection/fuel
systems,
motor seals and high-vacuum systems.

Advantages
This is a seal to prevent dust getting in, in order to protect
equipment and maintain the function of packing.
▪ Can be mounted to integrated groove.
· This is a rubber dust seal with double lip to prevent oil
spilling.
▪ Nitrile rubber and fluorine rubber are available, so it can be
used in a wide range of temperature conditions.
FAQ
